permute：Rearrange dimensions of N-D array
Syntax：B = permute(A,order)
Description：B = permute(A,order) rearrangesthe dimensions of A so that they are in the orderspecified by the vector order. B hasthe same values of A but the order of the subscriptsneeded to access any particular element is rearranged as specifiedby order. All the elements of order mustbe unique, real, positive, integer values.
Examples
Given any matrix A, the statement
permute(A,[2 1])
is the same as A.'.
For example:
A = [1 2; 3 4]; permute(A,[2 1])
ans =
1 3
2 4
The following code permutes a three-dimensional array:
X = rand(12,13,14);
Y = permute(X,[2 3 1]);
size(Y)
ans =
13 14 12
