Question
Compute the convolution f * f of the function ƒ (defined below) with itself:
1
f(r) = -e
-z²/20²
w
You can assume that o is a positive real number. Tell me if the convolution is wider or
narrower than the original Gaussian.
Note that while I don't care much about overall multiplicative factors of 2 or a in front of the
function, I care very much about the value of the exponent. Factors of 2 in the exponent are crucial
here, so be careful.
