You need a sequence of images, not a whole workspace which could contain dozens of unrelated variables. Then use the VideoWriter class.

You might also want to look at my demo http://www.mathworks.com/matlabcentral/answers/81210#answer_90938

yes sir this is fine..what u have suggested.. but while I am using the .mat workspace file as the source and the matrix viewer as the destination I can easily view the video but when I am using the To multimedia file as the destination the video is not getting saved as the original file which I could see in the matrix viewer... In other words I have got the .mat workspace variable which contains the video and I need to have the same video file in .avi format...
