Can MATLAB for 64 bit use pre-compiled 32 bit mex files?

Question

I have access to a library with pre-compiled 32 bit mex files (Windows: .mexw32, Linux: .mexa32). I am having a hard time compiling the library myself for a 64 bit machine, so I was wondering if there is a way to make MATLAB 64 bit work with 32 bit mex files.

As far as I know you're out of luck. Take your compilation troubles as a demonstration why interpreted languages like Matlab are so awesome. — Jonas

In general accessing 32bit code from a 64bit executable is nontrivial. Therefore I doubt they have implemented this in MATLAB natively...

No a 64-bit program cannot use 32-bit shared libraries. One option is to install the 32-bit version of MATLAB on your machine as well.
