Permutation allocation
- Function: gsl_permutation * gsl_permutation_alloc (size_t n)
-
This function allocates memory for a new permutation of size n.
The permutation is not initialized and its elements are undefined. Use
the function
gsl_permutation_calloc
if you want to create a
permutation which is initialized to the identity. A null pointer is
returned if insufficient memory is available to create the permutation.
- Function: gsl_permutation * gsl_permutation_calloc (size_t n)
-
This function allocates memory for a new permutation of size n and
initializes it to the identity. A null pointer is returned if
insufficient memory is available to create the permutation.
- Function: void gsl_permutation_init (gsl_permutation * p)
-
This function initializes the permutation p to the identity, i.e.
(0,1,2,...,n-1).
- Function: void gsl_permutation_free (gsl_permutation * p)
-
This function frees all the memory used by the permutation p.
- Function: int gsl_permutation_memcpy (gsl_permutation * dest, const gsl_permutation * src)
-
This function copies the elements of the permutation src into the
permutation dest. The two permutations must have the same size.
