Divide a square matix with given rows or column index

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?
