for K = 1 : 3
A{K+1} = A{K}*A{1};
figure(); surf(A{K+1}); title("iteration " + K)

this is not working with me actualli, because i have two matrix that i need to plot.
U is 401x26 matrix
xx is 401x1 matrix
i am putting this condition to be solved. but does not looks like good. even i am obtaining three different graphes. not all three in same figure. could you help me with this. thanks
for cc=1:3
if cc==1,
figure(1); hold on; plot(xx,U(:,26)); title("iteration " + cc)
elseif cc==2,
figure(2); hold on; plot(xx,U(:,26)); title("iteration " + cc)
else
figure(); hold on; plot(xx,U(:,26)); title("iteration " + cc)
end
end

for cc = 1 : 3
U(:,26) = U(:,26) + randn(size(U,1),1); %or whatever change is appropriate
plot(xx, U(:,26))
title("iteration " + cc);
hold on
end
