perms
All possible permutations
P = perms(v)
P = perms(v),
where v is a row vector of length n, creates a matrix whose rows consist of all possible permutations of the n elements of v. Matrix P contains n! rows and n columns.
The command perms(2:2:6) returns all the permutations of the numbers 2, 4, and 6:
6 4 2 4 6 2 6 2 4 2 6 4 4 2 6 2 4 6This function is only practical for situations where
n is less than about 15.
nchoosek All combinations of the n elements in v taken k at a
time
permute Rearrange the dimensions of a multidimensional array
randperm Random permutation
