Hi I am currently working on a 64 bit version of matlab(2015 ra).I have a mex file prematch_mex.mexw32 .whenever i am runnig the main function it is always showing the same error function not defined.( I have chekd that it is in the path).How to run a mex a 32bit file in a 64 bit version of matlab?
And one more important thing ,i also have a file named prematch_mex.mexglx . wht is this extension = .mexglx ????
I am working on windows

.mexglx files are for Linux.
You cannot use a .mexw32 with 64 bit MATLAB. You will need to get the source recompiled to 64 bit version, or else you will need to use 32 bit MATLAB (which can be run even on 64 bit MS Windows systems.)

@Walter Roberson that means i have no choice but to download a 32 bit matlab instead?

Of course you have choices. For example you could track down the authors and request that they provide you with a 64 bit version. You could write the functionality yourself. You could hire the authors to provide a 64 bit version. You could get permission from the authors to decompile (but only after you read the matlab terms and conditions about Derived Works and what you can do with them.) You could write a wrapper program that allows 64 bit programs to call 32 bit DLL and somehow write the interface without reverse engineering the interface in violation of the Mathworks Terms of Use. You could contract with Mathworks for permission to perform the necessary reverse engineering. You could hire Mathworks to build such an interface.
And willfully violating a license agreement is always an option. You might not like the potential consequences but it is an option.

This is a stab in the dark, but a Google search found this on GitHub. If that is the package you are using, the MEX files here have .mexw64 versions, which is what you need for 64-bit MATLAB on Windows.

That was a search Above and Beyond The Call Of Duty, Ken ;-)

@Ken Atwell thank you and one more question why is the 64 bit version code taking longer time than the 32 bit one????
