Hello

What does the '@' symbol do in this equation?

Is the first (z) multiplied the e^(...)?

thank you

% Gaussian kernel function kerf=@(z)exp(-z.*z/2)/sqrt(2*pi);

Accepted answer

It is a function handle. It means that you are defining an anonymous function 'kerf' that takes z as an input. The actual equation is just

exp(-z.*z/2)/sqrt(2*pi)

The User Guide has a pretty good write-up about these. Search "anonymous function" in the Help.
