matrix inside a matrix

I am working on building an energy momentum relationship (E-K diagram) for a semiconductor. I am treating my periodic system with 100 unit cells and so i have a 100-by-100 matrix. The matrix is such that all the diagonal elements look like the same (say 3 3 3 ...... all across the diagonal), all the upper diagonal elements look the same (2 2 .......)and all the lower diagonal elements look the same too. The problem is i havent been able to build my 100 by 100 matrix when the diagonal elements look like say 3 4 5 3 4 5 3 4 5 ............ The same thing goes for the variation in upper and lower diagonal elements. Can anyone please help me what sort of command should i use?
