Permutations

Class methods

GSL::Permutation.new(n)

GSL::Permutation.alloc(n)

These functions create a new permutation of size n. The permutation is not initialized and its elements are undefined. Use GSL::Permutation.calloc if you want to create a permutation which is initialized to the identity.

GSL::Permutation.calloc(n)

This creates a new permutation of size n and initializes it to the identity.

Methods

GSL::Permutation#init()

This initializes the permutation to the identity, i.e. (0,1,2,...,n-1). 

GSL::Permutation#get(i)

Returns the value of the i-th element of the permutation.

GSL::Permutation#swap(i, j)

GSL::Permutation#size

GSL::Permutation#valid

GSL::Permutation#reverse

GSL::Permutation#inverse

GSL::Permutation#next

GSL::Permutation#prev

GSL::Permutation#fwrite(filename)

GSL::Permutation#fread(io)

GSL::Permutation#fread(filename)

GSL::Permutation#fprintf(io, format = "%u\n")

GSL::Permutation#fprintf(filename, format = "%u\n")

GSL::Permutation#fscanf(io)
