Matlab - Transpose a 3D matrix only in the third d

2020-03-17 04:22发布

问题:

I have a 3 x 3 x 2 matrix, for example :

M(:,:,1) =
     1     2     3
     4     5     6
     7     8     9

M(:,:,2) =
    10    11    12
    13    14    15
    16    17    18

and I would like to transpose each M(:,:,i), I mean I would like to have :

M(:,:,1) =
     1     4     7
     2     5     8
     3     6     9

M(:,:,2) =
    10    13    16
    11    14    17
    12    15    18

How is it possible to do this without loops ? Thank you very much !

That's what permute does:

result = permute(M, [2 1 3]); %// swap dimensions 1 and 2
