length

PURPOSE

SYNOPSIS

DESCRIPTION

 length(p) gives the size of the permutation

CROSS-REFERENCE INFORMATION

• length length(p) gives the size of the permutation

• cycles cycles(p) returns a cell array containing the cycle structure of p
• display display(p) --- display a permutation in disjoint cycle form.
• eq test if p == q
• length length(p) gives the size of the permutation
• longest_cycle longest_cycle(p) -- return the length of the longest cycle in p
• matrix matrix(p) gives a permutation matrix version of p
• miss miss(p) -- maximum increasing subsequence
• mpower p^t is p multiplied by itself t times. May have t <= 0.
• mtimes p*q is the composition of p and q
• permutation constructor for the permutation class
• random random(p) --- return a random reordering of the elements of p
• sign sign of a permutation (1 for even, -1 for odd)
• size size(p) returns the number of elements permuted and the number of cycles.
• subsref p(k) returns the result of p applied to k.
