Hello,
I m compiling with Matlab2013a(8.1) and I m getting a Segmentation violation Fatal Error. I ve read similar cases and I assume this happens because I add the whole m flder of my project and there is a conflict that I cannot resolve.
As my code has many feval I cannot add %#function to each function to denote them for the compiler; Thus I have to add the whole source folder (m). However when I do so, I have the following error.
Any help would be highly appreciated.
Thank you
Lia

There is a hint in that error message that you might be attempting to compile a function that uses the Symbolic Toolbox in a section that is not protected by if ~isdeployed() . It is not necessarily in any function that would actually be called: it could be in some function that just happens to be in the same folder, since you are adding in the entire folder.
If this is the case, then you have the problem that nothing about the Symbolic Toolbox can be compiled.
