hypot() [8/10]

var stan::math::hypot ( const var &  a, const var &  b  )

inline

Returns the length of the hypotenuse of a right triangle with sides of the specified lengths (C99).

The partial derivatives are given by

\(\frac{\partial}{\partial x} \sqrt{x^2 + y^2} = \frac{x}{\sqrt{x^2 + y^2}}\), and

\(\frac{\partial}{\partial y} \sqrt{x^2 + y^2} = \frac{y}{\sqrt{x^2 + y^2}}\).

Parameters

[in]	a	Length of first side.
[in]	b	Length of second side.

Returns

Length of hypotenuse.
