How to make differently named movies in a for-loop in matlab

Say i have a for-loop. 

count=1;
for t=1:20

    while(true)
        figure();
       (do sth...)
       view([-90 -90])
       pause(0.01)
       M(count)=getframe;
       count=count+1;
     end

movie2avi(M, 're.avi');
end

Inside the for-loop there is a while loop where i am making my movie. But in each iteration of for loop one movie is made. I want to store each movie with name as re1, re2,...re20,etc. How to do modify the command movie2avi(M, 're.avi'); to do it?

Convert the index t to a string using num2str and concatenate:

movie2avi(M, ['re',num2str(t),'.avi']);

This will generate re1.avi,re2.avi,...,re20.avi.

For better sorting of the files, you may want to add a leading 0 to the filenames as well:

movie2avi(M, ['re',num2str(t,'%02G'),'.avi']);

This will generate re01.avi,re02.avi,...,re20.avi. The extra argument '%02G' is a formatspec that creates an integer-looking string of at least length 2 with zeros padding numbers of length 1.
