NAME

diag - get diagonal part of a matrix

DESCRIPTION

This function get the diagonal part of a matrix. csr<Float> a; dia<Float> d = diag(a);

TODO

Build a csr matrix from a diagonal one or from a vector: dia<Float> d; csr<Float> a = diag(d); vec<Float> u; csr<Float> b = diag(u);

IMPLEMENTATION
