Generate all permutations of a vector

This function generates all possible permutations of the elements in a given vector x. The result is returned as a matrix, where each row represents a unique permutation of the input vector.

Usage

permute(x)

Arguments

x

A vector of elements to permute. The elements can be of any type, but they should be unique for meaningful permutations.

Value

A matrix where each row is a unique permutation of the input vector x.
