- A(i) outputs a scalar. You want A(:,i), which outputs the i:th column
- your code displayed a dot, which was difficult to see

I would like to use for loop to plot data from matrix A together with the corresponding column of matrix B using sub plot function. Below is my initial code. The problem is that I don't see any thing on the plots. Any help/suggestions would be appreciated.
X=1:1:100;
A=randi([1 10],100,3);
B=A+2;
hold on
for i=1:3
subplot(3,1,i)
plot(X,A(i));
plot(X,B(i));
end
