Hi. My question might sound naive but can u please explain me in detail as to how to change the extension of a file from .wav to .res using MATLAB. P.S. all my files are stored in different names in the same folder

Do you want to change the extension or change the format? Renaming a file is very different from converting a file.

The MATLAB command to rename files is movefile()

Supposing you just want to rename the file, do this
! ren temp.wav temp.res

This is a C-Mex, which is about 20 times faster than MATLAB's movefile under Windows (I do not have a measurement under Linux):

For renaming you should be able to extrapolate from the second example at:
http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
you can use either the MATLAB movefile command or use the ! to invoke a system command to use your OS built in move/copy/rename command.

This was thought as a comment to Walter's answer, but the "Save" button of the comments is currently not working - on my computer.

@Arturo: It seems liek you have tried it three times?! ;-)
I'm not able to create a question also. I've sent a message to fiels@mathworks already.
Now I'm trying it with an alternative browser...
