Hello,
I used Matlab Coder to generate a randn mexFunction and used it in another mexFunction. The code runs perfectly well on two computers but not on the third one. Matlab said can't find randn1.mexw64.
What could have happened?
Thanks.

Hi,
perhaps the third computer is a 32bit MATLAB/Windows? Just enter
mexext
in the 3rd computer. If it returns mexw32, you have to generate and compile the code on the 3rd computer again ...

Thanks for the reply. Unfortunately the module which was not found was generated with Matlab Coder. I did not at all use Visual C++ to write this mexFunction. It is just the normal Matlab randn function generated by Coder.

It is true that other DLLs on which the mexFunction depends are not found. I used dependencywalker.exe to check it. The missing DLLs are libmx.dll, libmex.dll, libemlrt.dll and libmwmathutil.dll.
What can I do to make this mexFunction find these files ?

I have read somewhere that a possible solution is to use dependencywalker to check the required files needed to run the mexFunction.
I have tried that and here are the missing files: libmx.dll libmex.dll libemlrt.dll libmwmathutil.dll
What should I do to make the mexFunction find these missing .dll files?
Thanks.

After I add bin/win64 folder to systen path and relaunch the dependencywalker, now the Mathwork dlls got resolved, and further walking reveals new missing dlls.

API-MS-WIN-CORE-PRIVATEPROFILE-L1-1-1.DLL
