A friend of mine is doing the exact same code
My code:
A = 4;
W = 0.6;
T = 0:10;
x = A*cos(W'*T')
plot(T',x')
title('Displacement versus Time')
xlabel('Time')
ylabel('Displacement')
Index exceeds the number of array elements (24).
Error in Assignment1Q3 (line 6)
title('Displacement versus Time')%Name of graph
His code
% Plot the dispalcment vs the time
plot(t,x,'Linewidth',2)
title('Displacement vs Time')
xlabel('Time in s')
ylabel('Displacement in cm')
Why am I getting this error and he is not? I am really unsure when we have just named them different things, but the layout is excatly the same. I am pretty new to Matlab and I'm not even sure if this is the right place to post the question. If it isn't please point me in the right direction.
Thanks, Liam

Try to clear the variables, before using your code. There is no error in your code. It should work.
clc; clear all;
A = 4;
W = 0.6;
T = 0:10;
x = A*cos(W*T)
plot(T,x)
title('Displacement versus Time')
xlabel('Time')
ylabel('Displacement')

It means, there is a variable named title in your workspace....clear all/ clear title should have helped.
