How to reshape this matrix?
显示 更早的评论
Currently I have 3 dimensional matrix of size (2,3,3)
A(:,:,1) =
1 2 3
4 5 6
A(:,:,2) =
7 8 9
10 11 12
A(:,:,3) =
13 14 15
16 17 18
I would like to reshape it into [6 3] matrix so that it will become
A =
1 2 3
4 5 6
7 8 9
10 11 12
13 14 15
16 17 18
I try to use reshape(A,[6 3]); But it return the wrong matrix
Is there any quick way to do this?

Test matrix
A = rand(2,3,3);
Solution #1
D = reshape(permute(A, [1 3 2]), [6 3])
Solution #2
B = mat2cell(A, 2, 3, [1 1 1]); % slice into 3 cells (along dim 3)
C = squeeze(B); % flatten from dim 3 to dim 1
D = vertcat(C{:}); % vertically append the three matrices
