Hey guys,
Annoying problem...but I'm new to matlab.
I have a function f=@(x)(x-2.5).*exp(-0.5)*(x-2).^2)+0.2. I want to calculate f(-1)*f(0). How do you do it?
I need to specify a bit. I'm confused on how to calculate f(x) for any number I want. Like, if I want the answer of f(8) of the equation how do I compute it in matlab?

Try it this way:
workspace; % Make sure workspace panel is showing.
% Define function
f=@(x)(x-2.5).*exp(-0.5*(x-2).^2)+0.2
% Compute some results
r1 = f(8)
r2 = f(-1)
r3 = f(0)
r4 = r2 * r3

Britney, I think our answers crossed and you got it working now. So please mark the answer as Accepted if we're done.

if I type f(8) in command window it works. I get the same answers as Image Analyst. I think i tried typing f(8) in a different script and that is why it didn't work. But it all works now.
Thank you guys for your help!!
