The use of compiled (and possibly compiler-optimised) code can offer significant processing speed advantages over equivalent interpreted functions (e.g. .m files) for computationally intensive procedures. The C++ code generated by @strong{MTT} allows the same code to be generated as standalone code, Octave .oct files or Matlab .mexglx files. Although @strong{MTT} usually takes care of the compilation options, if it is necessary to compile the code on a machine on which @strong{MTT} is not installed, the appropriate flag should be passed to the compiler pre-processor: @itemize @bullet @item @code{-DCODEGENTARGET=STANDALONE} @item @code{-DCODEGENTARGET=OCTAVEDLD} @item @code{-DCODEGENTARGET=MATLABMEX} @end itemize @node Simulation output, , Simulation code, Simulation @comment node-name, next, previous, up @section Simulation output @cindex Simulation output The view (@pxref{Views}) representation provides a graphical representation of the results of a simulation; the postscript language provides the same thing in a form that can be included in a document. |
