MATLAB help... how to define this simple input function?

Question

I have to test a transfere fucntion with this input to use the lsim function...

Time range is define as...
t=1:10;

input function is t square divide by 11, as in (t^2)/11. How do I define this function?

when I put v=(t^2)/11, I get some error about the matrix, saying it should be square matrix... I think it has something to do with the time range but I don't know what to do

Anyone can pls help me out... thank you...

I tried the suggested v=(t.*t)/11

for v, it does works but unfortunately when I run lsim(num,den,t,v) fucntion, it says error, time vector must be evenly spaced... thanks again

Answer 1

there is nothing wrong with ur range. Just define the function as v= (t.*t)/11
