     Independent(</span></font><i><font color="black"><span style='white-space: nowrap'>u</span></font></i><font color="blue"><span style='white-space: nowrap'>);<br/>      </span></font><i><font

style='white-space: nowrap'><br/>      </span></font><i><font color="black"><span style='white-space: nowrap'>v</span></font></i><font color="blue"><span style='white-space:

     Independent(</span></font><i><font color="black"><span style='white-space: nowrap'>u</span></font></i><font color="blue"><span style='white-space: nowrap'>);<br/> </span></font></code> Before the call to <a href="independent.xml" target="_top"><span style='white-space: nowrap'>Independent</span></a> , <code><i><font color="black"><span style='white-space: nowrap'>u</span></font></i><font color="blue"><span style='white-space: nowrap'>[0]</span></font></code> is a <a href="glossary.xml#Parameter" target="_top"><span style='white-space: nowrap'>parameter</span></a> and after the call it is a variable. Thus in the first case, <code><i><font color="black"><span style='white-space: nowrap'>v</span></font></i></code> is a variable and in the second case it is a parameter. <br/> <br/> <b><big><a name="Bugs" id="Bugs">Bugs</a></big></b> <br/> What should I do if I suspect that there is a bug in CppAD ? <code><span style='white-space: nowrap'><br/> <br/> </span></code><ol type="1"><li>The first step is to search this page for mention of some feature that perhaps you interpreting as a bug (and is not). If this does not solve your problem, continue to the next step. </li><li> The second step is to check the <a href="whats_new.xml" target="_top"><span style='white-space: nowrap'>whats_new</span></a> messages from the date of the release that you are using to the current date. If the bug has been mentioned and fixed, then <a href="install.xml" target="_top"><span style='white-space: nowrap'>install</span></a> the current version of CppAD. If this does not solve your problem, continue to the next step. </li><li> Send an e-mail message to the mailing list <a href="http://list.coin-or.org/mailman/listinfo/cppad" target="_top"><span style='white-space: nowrap'>cppad@list.coin-or.org</span></a> with a description of the bug. Attaching a small source code sample program that demonstrates the bug is always helpful. The smaller the program, the better the bug report. </li></ol> <br/> <br/> <b><big><a name="CompareChange" id="CompareChange">CompareChange</a></big></b> <br/> If you attempt to use the <a href="comparechange.xml" target="_top"><span style='white-space: nowrap'>CompareChange</span></a> function when <code><font color="blue">NDEBUG</font></code> is true, you will get an error message stating that <code><font color="blue">CompareChange</font></code> is not a member of the <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a> template class. <br/> <br/> <b><big><a name="Complex Types" id="Complex Types">Complex Types</a></big></b> <br/> Which of the following complex types is better: <code><font color="blue"><span style='white-space: nowrap'><br/>      AD< std::complex<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>> ><br/>      std::complex< AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>> ><br/> </span></font></code> The <a href="abs.xml#Complex Types" target="_top"><span style='white-space: nowrap'>complex abs function</span></a> is differentiable with respect to its real and imaginary parts, but it is not complex differentiable. Thus one would prefer to use <code><font color="blue"><span style='white-space: nowrap'><br/>      std::complex< AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>> ><br/> </span></font></code> On the other hand, the C++ standard only specifies <code><font color="blue"><span style='white-space: nowrap'>std::complex<</span></font><i><font color="black"><span style='white-space: nowrap'>Type</span></font></i><font color="blue"><span style='white-space: nowrap'>></span></font></code> where <code><i><font color="black"><span style='white-space: nowrap'>Type</span></font></i></code> is <code><font color="blue">float</font></code>, <code><font color="blue">double</font></code>, or <code><font color="blue">lone double</font></code>. The effect of instantiating the template complex for any other type is unspecified. <br/> <br/> <b><big><a name="Exceptions" id="Exceptions">Exceptions</a></big></b> <br/> Why, in all the examples, do you pass back a boolean variable instead of throwing an exception ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>The examples are also used to test the correctness of CppAD and to check your installation. For these two uses, it is helpful to run all the tests and to know which ones failed. The actual code in CppAD uses the <a href="errorhandler.xml" target="_top"><span style='white-space: nowrap'>ErrorHandler</span></a> utility to signal exceptions. Specifications for redefining this action are provided. <br/> <br/> <b><big><a name="Independent Variables" id="Independent Variables">Independent Variables</a></big></b> <br/> Is it possible to evaluate the same tape recording with different values for the independent variables ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>Yes (see <a href="forward_zero.xml" target="_top"><span style='white-space: nowrap'>forward_zero</span></a> ). <br/> <br/> <b><big><a name="Math Functions" id="Math Functions">Math Functions</a></big></b> <br/> Are there plans to add more math functions to CppAD ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>Yes. The <a href="std_math_ad.xml" target="_top"><span style='white-space: nowrap'>std_math_ad</span></a> and <a href="mathother.xml" target="_top"><span style='white-space: nowrap'>MathOther</span></a> section contains a list of the math functions included so far. Contact the mailing list <a href="http://list.coin-or.org/mailman/listinfo/cppad" target="_top"><span style='white-space: nowrap'>cppad@list.coin-or.org</span></a> if you need a math function that is has not yet been included. <br/> <br/> <b><big><a name="Matrix Inverse" id="Matrix Inverse">Matrix Inverse</a></big></b> <br/> Is it possible to differentiate (with respect to the matrix elements) the computation of the inverse of a matrix where the computation of the inverse uses pivoting ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>The example routine <a href="lusolve.xml" target="_top"><span style='white-space: nowrap'>LuSolve</span></a> can be used to do this because the inverse is a special case of the solution of linear equations. The examples <a href="jac_lu_det.cpp.xml" target="_top"><span style='white-space: nowrap'>jac_lu_det.cpp</span></a> and <a href="hes_lu_det.cpp.xml" target="_top"><span style='white-space: nowrap'>hes_lu_det.cpp</span></a> use LuSolve to compute derivatives of the determinant with respect to the components of the matrix. <br/> <br/> <b><big><a name="Mode: Forward or Reverse" id="Mode: Forward or Reverse">Mode: Forward or Reverse</a></big></b> <br/> When evaluating derivatives, one always has a choice between forward and reverse mode. How does one decide which mode to use ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>In general, the best mode depends on the number of domain and range components in the function that your are differentiating. Each call to <a href="forward.xml" target="_top"><span style='white-space: nowrap'>Forward</span></a> computes the derivative of all the range directions with respect to one domain direction. Each call to <a href="reverse.xml" target="_top"><span style='white-space: nowrap'>Reverse</span></a> computes the derivative of one range direction with respect to all the domain directions. The times required for (speed of) calls <code><font color="blue">Forward</font></code> and <code><font color="blue">Reverse</font></code> are about equal. The <a href="seq_property.xml#Parameter" target="_top"><span style='white-space: nowrap'>Parameter</span></a> function can be used to quickly determine that some range directions have derivative zero. <br/> <br/> <b><big><a name="Namespace" id="Namespace">Namespace</a></big></b> <br/> <br/> <b><a name="Namespace.Test Vector Preprocessor Symbol" id="Namespace.Test Vector Preprocessor Symbol">Test Vector Preprocessor Symbol</a></b> <br/> Why do you use <code><font color="blue">CPPAD_TESTVECTOR</font></code> instead of a namespace for the CppAD <a href="testvector.xml" target="_top"><span style='white-space: nowrap'>testvector</span></a> class ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>The preprocessor symbol <small><a href="testvector.xml" target="_top"><span style='white-space: nowrap'>CPPAD_TESTVECTOR</span></a> </small> determines which <a href="simplevector.xml" target="_top"><span style='white-space: nowrap'>SimpleVector</span></a> template class is used for extensive testing. The default definition for <code><font color="blue">CPPAD_TESTVECTOR</font></code> is the <a href="cppad_vector.xml" target="_top"><span style='white-space: nowrap'>CppAD::vector</span></a> template class, but it can be changed. Note that all the preprocessor symbols that are defined or used by CppAD begin with either <code><font color="blue">CPPAD</font></code> (some old deprecated symbols begin with <code><font color="blue">CppAD</font></code>). <br/> <br/> <b><a name="Namespace.Using" id="Namespace.Using">Using</a></b> <br/> Why do I have trouble when the following command <code><font color='blue'><pre style='display:inline'> using namespace CppAD </pre></font></code> is at the global level (not within a function or some other limited scope). <code><span style='white-space: nowrap'><br/> <br/> </span></code>Some versions of <code><font color="blue"># include <cmath></font></code> for gcc and Visual C++ define the standard math functions, (for example <code><font color="blue"><span style='white-space: nowrap'>double sqrt(double </span></font><i><font color="black"><span style='white-space: nowrap'>x</span></font></i><font color="blue"><span style='white-space: nowrap'>)</span></font></code> ) at the global level. It is necessary to put your <code><font color="blue">using</font></code> commands within the scope of a function, or some other limited scope, in order to shadow these improper global definitions. <br/> <br/> <b><big><a name="Speed" id="Speed">Speed</a></big></b> <br/> How do I get the best speed performance out of CppAD ? <br/> <br/> <b><a name="Speed.NDEBUG" id="Speed.NDEBUG">NDEBUG</a></b> <br/> You should compile your code with optimization, without debugging, and with the preprocessor symbol <code><font color="blue">NDEBUG</font></code> defined. (The <a href="speed_cppad.xml" target="_top"><span style='white-space: nowrap'>speed_cppad</span></a> tests do this.) Note that defining <code><font color="blue">NDEBUG</font></code> will turn off all of the error checking and reporting that is done using <a href="errorhandler.xml" target="_top"><span style='white-space: nowrap'>ErrorHandler</span></a> . <br/> <br/> <b><a name="Speed.Optimize" id="Speed.Optimize">Optimize</a></b> <br/> It is also possible that preforming a tape <a href="optimize.xml" target="_top"><span style='white-space: nowrap'>optimization</span></a> will improve the speed of evaluation more than the time required for the optimization. <br/> <br/> <b><a name="Speed.Memory Allocation" id="Speed.Memory Allocation">Memory Allocation</a></b> <br/> You may also increase execution speed by calling <code><font color="blue">hold_memory</font></code> with <a href="ta_hold_memory.xml#value" target="_top"><span style='white-space: nowrap'>value</span></a> equal to true. <br/> <br/> <b><big><a name="Tape Storage: Disk or Memory" id="Tape Storage: Disk or Memory">Tape Storage: Disk or Memory</a></big></b> <br/> Does CppAD store the tape on disk or in memory ? <code><span style='white-space: nowrap'><br/> <br/> </span></code>CppAD uses memory to store a different tape for recording operations for each <code><font color="blue"><span style='white-space: nowrap'>AD<</span></font><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i><font color="blue"><span style='white-space: nowrap'>></span></font></code> type that is used. If you have a very large number calculations that are recorded on a tape, the tape will keep growing to hold the necessary information. Eventually, virtual memory may be used to store the tape and the calculations may slow down because of necessary disk access. <hr/>Input File: omh/faq.omh </body> </html> |
