mex

I've upgraded my MATLAB to 2014b (on OS X 10.10), and tried to test some old MEX C/C++ codes. As usual, I run mex -setup from the command window, and I would expect to be provided the chance to overwrite the option file "meshopt.sh". But now, it seems MATLAB has made some change and I am not allowed to change the MEX configuration, it simply says: MEX configured to use Xcode with Clang for C language compilation, ... to choose a different language, select one from the following mex -setup C++ mex -setup FORTRAN So, is it true that the old ways to modify "mexopts.sh" are no longer feasible? It

Currently trying to create a minimal example of scripted mex file generation. I have a MATLAB .m script that I am running to generate mex files. I would like to pass in all the arguments as variables so that I can automate a bunch of mex file construction when given a list of filenames/paths. #1 : unknown argument -outdir input = ' -outdir C:/Users/ian/mexTesting/mexFiles' mex('src/helloworld.cpp', input) #2 : unknown filepath / can't find location (interprets entire string as path to mex file) input = 'src/helloworld.cpp -outdir C:/Users/ian/mexTesting/mexFiles' mex(input) #3 : same issue as

I am trying to speeden up my Matlab program by writing a few functions in C++ and using the mex interface to integrate them. I got my results in a vector in c++. I want to transfer it to an array in MATLAB. I know i should redirect plhs[0] to the vector but i am not getting how exactly should I do it. When I've done similar things, I manually marshal the data so that it won't be freed when the C++ routine is completed. Here's a basic outline: #include <vector> #include "mex.h" mxArray * getMexArray(const std::vector<double>& v){ mxArray * mx = mxCreateDoubleMatrix(1,v.size(), mxREAL); std:

I have been trying to follow this example for compiling vtk in MATLAB using mex, on an Ubuntu 11.10. The mex command I used is as follows: mex -I/usr/include/vtk-5.6 vtk_file.cpp -L/usr/lib/ -lvtkFiltering -lvtkRendering -lvtkCommon After compilation I have a .mexa64 file. However, when I try to run the file I end up with the following error: Invalid MEX-file '/home/bill/Documents/MATLAB/vtk/vtk_file.mexa64': /usr/local/MATLAB/R2011b/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libvtkFiltering.so.5.6) How can I ensure that glibcxx is

On my computer I have Ubuntu 10.10 with gcc 4.4.4. I try to compile some mex files which use CUDA and I get following error message: >> cns_build('hmax') compiling... /home/leMe/hmax/cns/source/common_dec.h(54): warning: omission of exception specification is incompatible with previous function "operator new(size_t)" /usr/include/c++/4.4/new(91): here /home/leMe/hmax/cns/source/common_dec.h(55): warning: omission of exception specification is incompatible with previous function "operator new[](size_t)" /usr/include/c++/4.4/new(92): here /home/leMe/hmax/cns/source/common_dec.h(56): warning:
