Hi,
I have a square matix of size 10 x 10. I want to partition it by using given index of two rows and columns e.g. 2, 7. In that way, I will have seveal blocks of matrices. How do I get it?

Let's say your matrix is A.
>> blocks = mat2cell(A,[2,8],[2,8])
blocks =
2×2 cell array
{2×2 double} {2×8 double}
{8×2 double} {8×8 double}

Can't you just modify my example, changing the partitioning parameters to whatever it is you want?
