hypot

Square root of sum of squares (numerically stable).

Syntax

C = hypot(A, B)

Description

Returns sqrt(A.^2 + B.^2) computed in a way that avoids overflow when either argument is large or underflow when both are small. Common in computing 2D distances and amplitudes.

Example

hypot(3, 4)                % 5
