MATLAB: Running mexw64 files in R2013a Student version

32bit64bitMATLABmex files

I have Matlab Student version R2013a, which responds "mexw32" to the "mexext" command (even though I'm running it over Windows 8.1 64 bit). Is it possible to run a "mexw64" file on this version of Matlab or should I update it to a different/newer one?

Best Answer

mexext replies the extension matching to the currently running Matlab version. Obviously you have a 64 bit operating system but installed a 32 bit Matlab. Then it is not possible to run a mexw64 file.

It has many advantages to install a 64 bit Matlab instead.

You cannot do that. mexw64 files require a 64 bit OS to execute on.

In many cases if a mexw64 file is supplied then a mexw32 file is also available. But not always.

MATLAB: How to determine if I am running a 32-bit version of MATLAB or a 64-bit version of MATLAB

For MATLAB 7.8 (R2009a) and later versions, you can determine this information by selecting the "Help>About MATLAB" Menu from the desktop.

The information also appears on the splash screen as MATLAB is starting.

If you are running MATLAB without the desktop interface, the information appears in the command window when MATLAB starts.

For previous product releases, you can determine if the version of MATLAB you are running is 32-bit or 64-bit by using the following function:

computer

The following is the interpretation table to the ouptut of the above command:

 OUTPUT OF COMPUTER    VERSION OF MATLAB (32 bit / 64 bit)
 PCWIN                 32 bit MATLAB on Windows
 PCWIN64               64 bit MATLAB on Windows
 GLNX86                32 bit MATLAB on Linux
 GLNXA64               64 bit MATLAB on Linux

You can specifically probe for the MATLAB bitness by using the following command:

computer('arch')

This will return win64 for 64-bit MATLAB and win32 for 32-bit MATLAB.

You can also determine if you are running 32 or 64 bit MATLAB using the MEXEXT function which gives you the extension of the mex file generated by MATLAB:

 OUTPUT OF MEXEXT      VERSION OF MATLAB (32 bit / 64 bit)
 mexw32                32 bit MATLAB on Windows
 mexw64                64 bit MATLAB on Windows
 mexglx                32 bit MATLAB on Linux
 mexa64                64 bit MATLAB on Linux
 mexmac                32 bit MATLAB on Mac
 mexmaci               32 bit MATLAB on Intel-based Mac
 mexmaci64             64 bit MATLAB on Intel-based Mac
