Windows thinks .mat file should be opened with Microsoft Access

Up until now I have been able to view variables from .mat files in variable editor, either by opening the file with the open command in the workspace or by adding a breakpoint in my code (the current variables were automatically displayed in the variable editor). However, now I am not able to view variables from a .mat file in the variable editor.

I am using Windows 7, and I see that Windows started to recognize my .mat files as Microsoft access files. I cannot run the utility to change the file association, because I got this license through my university and when I try to run it I get the error message "??? Error using ==> fileassoc No permissions to modify the registry." I have changed the file association in Windows > Default Programs and right clicking the file, selecting "open with" and then selecting Matlab rather than Microsoft Access, but it still does not work.

I see that people who used Windows XP have posted solutions to this problem (<http://ask.metafilter.com/140324/How-do-you-open-MAT-files-with-variables>) but all of the options have changed in Windows 7. Does anyone have any guidance on this issue?

Probably it has something to do with size of new vectors you are trying to load.

Refer link from matlab documentation below ,for further information:

Hope it helps!!!!

Thank you SACHIN, my vectors are only 1x288 so I do not think it is the size.
