- Function: void gsl_permutation_reverse (gsl_permutation * p)
-
This function reverses the elements of the permutation p.
- Function: int gsl_permutation_inverse (gsl_permutation * inv, const gsl_permutation * p)
-
This function computes the inverse of the permutation p, storing
the result in inv.
- Function: int gsl_permutation_next (gsl_permutation * p)
-
This function advances the permutation p to the next permutation
in lexicographic order and returns
GSL_SUCCESS
. If no further
permutations are available it returns GSL_FAILURE
and leaves
p unmodified. Starting with the identity permutation and
repeatedly applying this function will iterate through all possible
permutations of a given order.
- Function: int gsl_permutation_prev (gsl_permutation * p)
-
This function steps backwards from the permutation p to the
previous permutation in lexicographic order, returning
GSL_SUCCESS
. If no previous permutation is available it returns
GSL_FAILURE
and leaves p unmodified.
