Most likely, the issue is not with matlab. There can be may reasons why a permission denied error occurs:
  • the file exists and is open by an application (matlab or something else)
  • you do not write access to the current directory
  • your antivirus is messing things up
  • this is on a network share and the file server has a rule blocking files with a pattern that match yours
  • etc.
Can you save the file with a different filename? Can you save it in a different location? Can you save any mat file?

Indeed that's been standard windows behaviour since Windows 7 for the OS to prevent you from writing files in the 'Program Files' directory. There are ways to bypass this but in any case, you really shouldn't be saving your mat files there. By default matlab home directory is in 'My Documents'. Why don't you save there.

It is true that i'm using windows. Stupid me to save all the files in the program file without notice it.
Thanks a lot Steven Lord and Guillaume. i know what to do now :-)
