_gr_vec_permute_inv, gr_vec_permute_inv

Synopsis#include <flint/gr_vec.h>
void _gr_vec_permute_inv(gr_ptr vec, slong * perm, slong len, gr_ctx_t ctx)source
int gr_vec_permute_inv(gr_vec_t dest, gr_vec_t src, slong * perm, gr_ctx_t ctx)source

Apply the inverse permutation: dest[i] = src[perm[i]]. The underscore version works in place and overwrites perm.
