#include <perm.h>

Detailed Description

Generic row/column permutation structure.

This data structure stores an $n\times n$ permutation matrix $P$ in an array 'perm' such that the operation $y \leftarrow Px$ is implemented by assigning y[i] = x[perm[i]] for 0 <= i < $n$ .

The transpose operation $y \leftarrow P^Tx$ is implemented by assigning y[perm[i]] = x[i].
