permute

Generalized transpose of a matrix, using a permutation vector.

Syntax

permute(A, P)

Inputs

A: Type: double | integer | char | string | logical | struct | cell; Dimension: scalar | vector | matrix
P: Type: integer; Dimension: vector

Outputs

R: The pemuted matrix.

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];
m(:,:,4) = [114, 124, 134, 144; 214, 224, 234, 244; 314, 324, 334, 344];
m(:,:,5) = [115, 125, 135, 145; 215, 225, 235, 245; 315, 325, 335, 345];
p=permute(m, [2,3,1])

p = 
slice(:, :, 1) = 
[Matrix] 4 x 5
111  112  113  114  115
121  122  123  124  125
131  132  133  134  135
141  142  143  144  145

slice(:, :, 2) = 
[Matrix] 4 x 5
211  212  213  214  215
221  222  223  224  225
231  232  233  234  235
241  242  243  244  245

slice(:, :, 3) = 
[Matrix] 4 x 5
311  312  313  314  315
321  322  323  324  325
331  332  333  334  335
341  342  343  344  345

Comments

The vector P must contain all explicit dimensions of A, and may also contain implicit higher singleton dimensions.
