MATLAB: This program is producing a STBC matrix of 8*4 32 times. how can i put them in a single matrix of 256*4 dimension?

putting 32 matrices in one

Best Answer

There is another end missing from you code. Assuming it should be added at the end, try changing:
SS = reshape(T(:,:,j),8,4);
to
SS(8*(i-1)+1:8*i,:) = STBC(:,:,i);
This gives a final SS matrix which is 256 x 4, although you'll have to verify if this the behaviour you want.
Also, I'm not sure what the purpose of the inner loop is - it seems like you're calculating the same thing 32 times.
