MATLAB: Does the MEX function call in MATLAB 7.5 (R2007b) not work in newer MATLAB versions while passing a series of source files

Question

I have created a MATLAB file that uses MEX as a function call to several flags and source files. This worked in MATLAB 7.5 (R2007b) but does not work in any of the new versions of MATLAB. For example, I have

source = ['file1' 'file2' 'file3']

And I want to pass it in a MEX command as follows:

mex(source,...)

However, I get an error about cannot find source.

Answer 1

The ability to pass a series of source files as a single string to the MEX function is not available in MATLAB 7.6+ (R2008a+).

In MATLAB 7.6+ (R2008a+) versions, the file checking routine is stricter. If a single string is passed in as an argument, it checks for a filename equivalent to the entire string and not as separate files. Therefore it is necessary to pass each filename as separate string instead of one.

Instead of

source = ['file1', 'file2', 'file3']
mex(source,..,..)

use

mex('file1','file2','file3',..,..)
