inserting submatrices within a larger matrix

Hello,

I am trying to add 4 different submatrices (4 x4 elements) along the diagonal of a a larger 16 x 16 matrix. the end result would look like:

submatrix_1 0...

0 0 0 0 sumatrix_2 0...

0 ... sumatrix_3 0 0 0 0

0 ... sumatrix_4

Any suggestions would be welcome! Thanks
