Preventing a MEX file from crashing in MATLAB

by

Which platform are you using? There are methods to help debug your MEX files. Whenever there is a segmentation fault, you can use an IDE to tell you where in the code it’s crashing.

Here are the directions for Mac OS: http://www.mathworks.com/help/matlab/matlab_external/debugging-on-mac-platforms.html

Here are the directions for Linux: http://www.mathworks.com/help/matlab/matlab_external/debugging-on-linux-platforms.html

Here are the directions for Windows: http://www.mathworks.com/help/matlab/matlab_external/debugging-on-microsoft-windows-platforms.html

NB: I am against referring the OP to a link off-site to help with his or her question. I usually include most of the answer in my posts and provide links as references. Because you haven’t told me what platform you’re using, I will not write solutions for all platforms as that will take too much time. As such (and I’m praying that the links are stable for a long time), you can refer to the appropriate link for your platform.
