What is the reason??

I have both Vista and XP running 2007a and there is no compatibility issues at all.<br> If, in 2007a, you type:<br> <br> help save<br> <br> you will see that there is a switch<br> <br> save filename -v7 <br> <br> in 2007a which allows a saved file to be read in version 7. You will have to use this switch in 2007a to load the file in 7.0 Fri, 21 Nov 2008 05:46:02 -0500 http://www.mathworks.com/matlabcentral/newsreader/view_thread/239651#612325 Amogh Rajanna Thank you very much<br> <br> version compatibility was the issue.<br> <br> i verified it and i was able to load the mat file in the XP matlab installation.<br> <br> Amogh Rajanna<br> &nbsp;
