# atan2

Version:

Computes the arctangent of y/x.

## Syntax

c = atan2(z)
c = atan2(y, x)

## z

Real or complex scalar or array of any dimension. atan2(z) is equivalent to atan2(real(z), imag(z)).

## y

Real or complex scalar or array of any dimension.

## x

Real or complex scalar or array of any dimension.

## c

Arctangent, in radians, of the elements in x and y. c is a scalar or an array of the same size as x and y.

## atan2 versus atan

The atan2 function can compute the arctangent for angles in any of the four quadrants of the x-y plane, whereas the atan function computes the arctangent in only two quadrants.

C = atan2(3, 4)
C = atan2(3+4i)
