error when saving: unable to write to MAT-file, File may be
in [Matlab]
|
From: Andrew Fiedler on 13 May 2010 09:52 I'm having the same problem with MATLAB R2009b (7.9.0.529). I seems completely random when it can save mat files and when it won't. Saving files to CSV in the same folder location works, and is a work-around for now but I have many programs that are already written to save MAT files which seem to fail for some inexplicable reason. Also, deleting the existing MAT files before trying to save new copies does not help.

Please contact Technical Support and work with them to determine the circumstances that cause this behavior so that if the problem is in MATLAB that we can correct it and if the problem is in some aspect of your configuration that you can take the appropriate action. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
