i am hoping some of the experts can help me out. i calculate a bunch
(144 to be precise) of 5 x 5 matrices to be used in an
eigenvalue/eigenvector calculation in a full 60 x 60 matrix. i cannot
seem to build the 60 x 60 in a way usable by Eigenvalues and
Eigenvectors because when I try things like
mat = {{M11, M12...},  ...}

with or without Flatten, it leaves the matrix brackets intact. Any
help would be greatly appreciated!
