You can use VideoWriter with MPEG-4 profile for this
v = VideoWriter('my-video.mp4','MPEG-4'); %uses h264 encoding
v.Quality = 80; %video quality
open(v);
writeVideo(v,myDataMatrix);
close(v);

Stricly speaking MPEG-4 can use other codecs than H.264. However, the documentation for VIdeoWriter does state that matlab uses H.264 for MPEG-4.
True, but we're still talking Matlab here, so indeed there's no other codec to choose from (I don't know why can't choose the codec though, maybe because h264 is supported by most devices/players).
