MATLAB: How to reshape a matrix

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

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)

m1 = [2 2; 0 0];
m2 =[1 1;0 0];
m3=[2 2 2 2 ;3 3 3 3];
C = {m1,m2,m3};
[r,c] = cellfun(@size,C);
m = max([r(:),c(:)]);
for ii = 1:numel(C)
    if any([r(ii),c(ii)] < m)
        C{ii}(m(1),m(2)) = 0;
    end
end
out = cat(1,C{:})

Two methods, I'll let you test which one is faster, probably the permute one:

B = reshape(permute(A, [1 3 2]), [], size(A, 2))

B = num2cell(A, [1 2]);
B = vertcat(B{:})
