OVERVIEW
conv(a,b) is used to take the convolution of two functions. Be sure to scale your output! 3:06
If you want the output to have the same number of terms as 'a', use conv(a,b,'same').

MATH CORRECTIONS/COMMENTS on the video -- PLEASE READ!!
1. f(t)*g(t) is said "f convolved with g".
2. at 4:15 we see the max value of the output = max f(t) times max g(t) -- know that this does not always happen.
3. Scaling the t-axis / x-axis is not always straightforward. My scale and shift works in this case but doesn't apply to the general case.
4. at 5:50 you don't need the .* for (1:length(yt))*dt because this is a vector times a scalar.
5. at 6:50 take note I have only included the t2(1) term. However, for the general case, you may use t2(1) + t1(1) to account for your signals starting at different times. In this video, t1(1) was simply zero and thus adding only t2(1) worked.
