Trying to combine multiple square matrices diagonally into a combined larger matrix

Im having trouble figuring out how to place square matricies diagonally within a larger combined matrix, does anyone know of a way of doing this? (Trying to create something like the above T matrix)(If the image is not clear i can upload another one)

You can use MATLAB's blkdiag function for this

so in your case

T = blkdiag(A,B,C)
