plot(t(1:length(y)),y,'g','Linewidth',2);

Index exceeds the number of array elements. Index must not exceed 501.

When you attach a picture of code, you make it far more difficult for someone to help you, since we are forced to retype your code completely.

What is worse, if you don't even show the error you got! Can we read your mind? I'm tryign, but the MATLAB crystal ball is foggy today.

Is there a good reason why you want to make it more difficult to get help, since it is trivial to paste in the text itself?

When you do give us the text, also paste in the COMPLETE ERROR MESSAGE. So EVERYTHING in red.

here is the code that is in the screenshot. Im sorry, this is the first question I have asked and did not know the exact specifics on how to post. The error that I am getting is "Index exceeds the number of array elements. Index must not exceed 501."

clear all

clc

t=0:0.01:5;

h=12.0 * exp(-2.0*t).*(t>= 0);

x=5* (t >= 0)-5* (t >=1.0);

y=conv(x,h,'full')*0.01;

figure;

subplot(3,1,1);

plot(t,h,'r','Linewidth',2);
