Dear all, I have a changing number of data to be analyzed. How can I do it the smart way without an if condition (copy and paste with ascending numbers) and without the "eval" instruction which I used to far. Simple example plotting two waves (with one if condition). How should I write the code to be flexible to plot 1, 2 or three waves, depending on the result (size(a,1)) I get? Looking forward to your advice. Thanks a lot!
t = 0:0.1:2*pi;
a = [sin(t); cos(t)];
figure
if size(a,1)==2
subplot(2,1,1)
plot(a(1,:))
subplot(2,1,2)
plot(a(2,:))
end

N = size(a,1)
for i=1:N
subplot(1,N,i), plot(a(i,:))
end

Yes, thanks - I see, my example was to simple. Indeed, this is the solution for the subplot, but I do have some uicontrol elements and variable names as well. This is what puzzles me, because I do not get along with the arrays in this case...

Please provide some example of your uicontrol elements and variable names and the code you have so far.
