Hi. I am trying to create a loop to multiply two matricies 40 times such that B*C=D1 and C*D1=D2 and B*D2=D3 and so on . I am very much new to matlab. Can anyone help me on this ?

What's the pattern? I know the product matrix is the right matrix the next time, but what about the left matrix? Does it alternate B, C, B, C, B, C, etc.?

Also, do you need to keep all the intermediate products, or just the final result?

The pattern is after you multiply by product of B*D by C then again have to multiply the product of C*(B*D) by B and simultaneously multiply thereafter products by C and B. I want all the intermediate steps as well.

Try this:

clc;
b = randi(9, 2, 2)
c = randi(9, 2, 2)
D{1} = b * c;
for k = 2 : 5 % End wherever you want
  theRemainder = rem(k, 2);
  % Alternate multiplying by b or c
  if theRemainder == 0
    D{k} = c * D{k-1};
  else
    D{k} = b * D{k-1};
  end
end
celldisp(D);
