Let's say I have such a matrix:
A=[1 3;2 4;2 5;0 0;4 5;4 7;0 0;5 6;0 0 ] %I want to divide it into submatrices limiting with [0 0]
B=[1 3;2 4;2 5] C=[4 5;4 7] D=[5 6]
Thank you for your time!

My question is beyond the extracting randomly rows and columns, meeting a condition to extract sub-matrices limted with [0,0]
Thomas 21 Mar 2014
You could easily find the [0 0] rows and use indexing to get the submatrices..
find(all(A==0,2))
ans =
4.00
7.00
9.00
These are your zero rows .. now index appropriately to create your new sub matrices..
