How to reshape a matrix

Hello,

For example I would like to reshape the following matrix

1 0 0 2 0 0

0 1 0 0 2 0

to

1 0 0

0 1 0

2 0 0

0 2 0

The number of horizontally stacked matrices is now 2,so the solution is easy b = [a(1:2,:); a(3:end,:)];

The question is now how to do this for n horizontally stacked matrices without using a loop? Does someone know?

Kind regards, Carlas

A = [1 0 0 2 0 0;  0 1 0 0 2 0];
B = reshape(permute(reshape(A, 2, 3, 2), [1, 3, 2]), 4, 3)

thanks!

if A is the first matrix that you defined, do:

B = [A(1:2,1:3);A(1:2,4:6)] to choose the required rows and columns from A to define B.

a(:,:,1)=eye(3,2);
a(:,:,2)=2.*eye(3,2);
B = reshape(permute(a, [1, 3, 2]),  size(a,3)*size(a,1),size(a,2))
