view .mexw32 (MEXW32 File) in Matlab R2011a

How can I view a file with ".mexw32" extension in Matlab R2011a? When I run it, this message appears:

??? Error using ==> Nonlin_Block15 MEX level2 S-function "Nonlin_Block15" must be called with at least 4 right hand arguments

What can I do?

If you do not have the source code, but only the compiled mexw32 file, you need to ask the author for the code. If he or she does not want to share the code, offering money is the usual method to initiate a collaboration.

Answer 2

[Andreas Goser]

You can't view this file - or at least it would mean nothing to you.

You can view and edit the source code likely a C code.

So for myname.mexw32, it is myname.c

thank you, but how I can view the file in C code? I only have the .mexw32 file best regards

[Andreas Goser]

Then you need to contact the author of the s function. One of multiple reasons for s fucntions is IP protection.

thank yooou

It looks like what you have is an S-function. You cannot run an S-function directly from MATLAB, it can only be called using an S-function block in Simulink.

[Mohammad Sadegh]

yes it is a S-function and I can call it in Simulink,but I want to know how the code is written so I can use it in my research. Hope u can help me
