Generalized reversing transpose of a matrix, using a permutation vector.
Syntax
ipermute(A, P)
Inputs
- A
- Type: double | integer | char | string | log
- P
- Type: integer
Outputs
- R
- The permuted input.
Example
m(:,:,1) = [111, 121, 131, 141; 211, 221, 231, 241; 311, 321, 331, 341];
m(:,:,2) = [112, 122, 132, 142; 212, 222, 232, 242; 312, 322, 332, 342];
m(:,:,3) = [113, 123, 133, 143; 213, 223, 233, 243; 313, 323, 333, 343];

The vector P must contain all explicit dimensions of A, and may also contain implicit higher singleton dimensions.
ipermute reverses the effect of permute when called with the same P.
