How do I recombine matrices in this order?

I have nine matrices with equal dimensions of 40x10, how do I recombine them in the way shown in my png?

Thank you

If your matrices are not together in a cell array, e.g. they're individually numbered matrices, then

• don't do that!
• fix the problem by putting them together in a cell array:

c = {M1, M2, M3, ....}

it is then trivial to reshape/transform that cell array and generate the full matrix you want:

c = reshape(c, 3, 3); %reshape the cell array in a 3x3 grid
c = rot90(c);  %rotate 90 degrees anticlockwise
result = cell2mat(c);  %concatenate all into one matrix

Thank you so much, you have saved me a lot of time :)
