I have a 119 x 49 x 27 (yxz) matrix (A) which is a stack of 27 blocks which make up a larger 2D image. I know that the larger 2D image has 3 x 9 (yx) =27 blocks. I am trying to 'stitch' together the 27 blocks to make the larger image. So far I've got:
B = reshape(A,49*9,119*3);
It generates a 2D matrix B (441 x 357) but is not correct.

it seems that the order than it joins the 27 blocks together is incorrect.

I'm not sure it can be done with reshape and permute alone. Temporarilly using a cell array, it's very easy:
A = permute(repmat(1:27, [119 1 27]), [1 3 2]); %demo matrix
B = num2cell(A, [1 2]); %split the stack into a cell array
B = reshape(B, 3, 9); %reshape the tiles into their final position. You may need to transpose the reshape
B = cell2mat(B); %convert to matrix
