fmpz_mat_randpermdiag
Synopsis
#include <flint/fmpz_mat.h>int fmpz_mat_randpermdiag(fmpz_mat_t mat, flint_rand_t state, const fmpz * diag, slong n)sourceSets mat to a random permutation of the rows and of the columns of the diagonal matrix whose first n diagonal entries are diag (and whose other entries are zero). Returns the parity of the permutation, 0 if it is even and 1 if it is odd. Requires n \le \min(r, c). Wrapper of gr_mat_randpermdiag.
