ipermute

Inverse permute — undo a permute operation.

Syntax

A = ipermute(B, order)

Description

Inverse of permute. If B = permute(A, order), then A = ipermute(B, order). Equivalent to permute(B, invperm(order)) where invperm is the inverse permutation.

Examples

A = magic(3);
B = permute(A, [2 1]);
isequal(ipermute(B, [2 1]), A)   % 1
