Hello all,
I want to compute the "diagonalizations" of some square and non-square
matrices over the integers. Given M \in GL_{m,n}(Z), I want square,
invertible matrices H,K (nxn and mxm respectively) such that M=HDK,
where D has the same dimensions as M and is zero everywhere except for
on the diagonal.
I've googled and look through the sage documentation, but I've found
nothing.
Thanks for any help!
