Permuted matrix
Web21. apr 2015 · C = ipermute (H, [3 1 2]) I need to separate the permuted vectors and change it back into separate planes and then finally recombine the planes to get a 3 dimensional … One way to represent permutations of n things is by an integer N with 0 ≤ N < n!, provided convenient methods are given to convert between the number and the representation of a permutation as an ordered arrangement (sequence). This gives the most compact representation of arbitrary permutations, and in computing is particularly attractive when n is small enough that N can be held i…
