hypotenuse
From learningr v0.29.1
by Richard Cotton
Dumb hypotenuse function.
Calculate the (Pythagorean) hypotenuse of two numeric vectors using the obvious algorithm.
Usage
hypotenuse(x, y)
Arguments
- x
A numeric vector.
- y
A numeric vector.
Value
A numeric vector of the hyptenuse of the inputs.
Note
This algorithm fails when the inputs are very large of very small, making it unsuitable for real-world use.
