This "code" isn't even finished...

Put a breakpoint in this line:
M=[M;V(i:i+I)];
and see what is happening in each iteration

"i" starts with 1. M becomes [V(1:(1+3))] = [1:4] = [1 2 3 4].
"i" becomes 5 = (1+J) = (1+4). M adds a row with [5 6 7 8]. Etc...
Ultimately, this will give you the numbers 1 through 12 in a 4x3 matrix.
1 2 3 4
5 6 7 8
9 10 11 12
Why use all that code when you could use: M=reshape([1:12], 4,3) ?
