mex error, no file name given

Hi,

I'm using mex. Although the help doc is pretty clear, using

   mex fname.xx

I cannot repeat it and am getting error.

e.g.

mex 3PK.SIF  or "3PK.SIF"
MEX: NO FILE NAME GIVEN. 
Usage: 
MEX ..... 
Use the -help option for more information....

What's the problem here? I'm using R2013a.

Thank you!

mex looks at the file extension to figure out how to compile the file. The .SIF file extension is unknown to mex, so it complains that it cannot find any files it does recognize such as .c .C .cpp .f files.

I would have thought that you would want to mex code to read SIF files, not a SIF file itself.
