MEX Files

MEX source files, and anything they call, must be compiled for a specific bitness. For example, 32-bit and 64-bit MEX files use different file name extensions (.mexw32 and .mexw64 respectively), so it is possible to have both 32-bit and 64-bit MEX binaries in the same folder.

Differences in the MEX API to support large data sets may require some accommodation. See How Do I Update MEX Files to Use the Large Array Handling API  for further discussion.

MAT Files

With large data sets that use the -7.3 MAT-file format, it is possible for the 64-bit version of MATLAB to produce a MAT-file that is too large for the 32-bit version of MATLAB.

Functional Differences Between 32-bit and 64-bit MATLAB

There are a small number of functional differences between the 32-bit and 64-bit versions of MATLAB. This table summarizes the differences:
