That's a dimension that has a length of 1. For example, if you had a 3D image that is 400 rows by 1 column by 200 slices, the second dimension (columns) would be a singleton since it's one. You'd have only one image plane running in the y-z direction (rows-slices). You can get back to a 2D image by using squeeze() to remove the singleton dimension.

I've a doubt here, M3d = randi(9, 2, 4, 3)
What does '9' indicate in the above command?

That is the max value that the random numbers in the 2-by-4-by-3 three-D matrix can take on. Did you look up randi in the help documentation? It describes it there.
