WebThe distance function returns the distance between two points. The distance of two points is the length of the vector d = p0 - p1, that starts at p1 and points to p0. The input parameters can be floating scalars or float vectors. In case of floating scalars the distance function is trivial and returns the absolute value of d. WebJan 11, 2024 · That is, function A can call function B, which itself calls function A. Indeed, function A can call itself.
