MATLAB: Can I use Matlab Coder generated Mex functions on another computer

matlab codermex

I've been able to use Matlab Coder to generate Mex Functions that work on my computer; but I cannot find any instructions on how to use these Mex functions on other computers that have Matlab (and that don't have Matlab Coder). Is there a straight forward way to move the c-code it generates to another system to create the mex function?

Quoting the documentation:

 To run a MEX function generated by MATLAB Coder&trade;, you must have licenses for all the toolboxes that the MEX function requires. For example, if you generate a MEX function from a MATLAB algorithm that uses a Computer Vision System Toolbox&trade; function or System object, to run the MEX function, you must have a Computer Vision System Toolbox license.

The other computer should also match the architecture of the computer on which the MEX function was generated.

Are you having any specific issues when you try to run the MEX function on another machine?

MATLAB: Call a mex file and using coder

The thing about mex files is they require MATLAB to run (MATLAB executable). MATLAB coder can generate more generic c-code that can be utilized independent of MATLAB so if you try to call a mex-file from this code you may run into issues.

It sounds like you already know what to do and you can use the ceval command directly on the C-code that the mex file utilizes.

MATLAB: Using a .mexw64 in a mexFunction

Either insert the C-source of function1.c without the mexFunction gateway to function2.c. Or call function2 through mexCallMATLAB:

mxArray *Input[1];
Input[1] = mxCreate...
mexCallMATLAB(0,NULL,1, Input, "function2");

The later is less efficient due to the double overhead of calling Matlab to call the mex.
