- 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.
