get the video saved from a movie frame

Hi, Can you provide me with source code lines to get a video saved in the file from a movie frame generated by this source code: for t=1:T mesh(data(:,:,t)); axis([-(ceil(dim/2)-1) floor(dim/2) -(ceil(dim/2)-1) floor(dim/2) -0.5 0.5]); M(t)=getframe; pause (0.05); end where data is a space-time signal varying over the time (T) and of size (dim,dim,T) Thank you in advance.
