How do you write this equation correctly in MATLAB?

[Star Strider]

That is difficult to read. It appears to be this:

p = @(delta,sigma) (exp(-sigma./delta)./delta) .* (sigma >= 0);

It will default to being 0 for sigma < 0, so it is not necessary to specifically include that condition.

Call the ‘p’ anonymous function with the two arguments as you would any other function.
