MATLAB: How to recombine matrices in this order

matrixmatrix manipulation

I have nine matrices with equal dimensions of 40×10, 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
