Here is my code.
Z=[3 1 7];
for i=1:length(Z);
A(i)=Z(i)+2
B(i)=Z(i)-7
C(i)=Z(i)+4
col=['g' 'b' 'r'];
for j:length(col)
x=[1 2 3];
y(:,i)=[A(i) B(i),C(i)];
subplot(3,1,i)
plot(x,y(:,i),'color',col(j))
end
end
My last line of code is failing to change the color on the plots. All of the plots end up red. I want one of the plots to be green, one to be blue, and one to be red. How can I fix my code?

They will be if you change the ‘col’ subscript from ‘j’ to ‘i’:
plot(x,y(:,i),'color',col(i))
because you subscripted the subplots by ‘i’.
