atan2

Contents: Description, Arguments, Usage, Examples, Related Functions Supported Under Version: >1.69 Current Davinci Version: 2.27 64-bit Safe: Yes Description Computes the trigonometric arc-tangent given the delta y and delta x values. This function also deals with data from 0 to 2pi and will not fail when the arc-tangent function becomes undefined. Consequently atan only deals with data from -pi/2 to pi/2 and fails when the arc-tangent function becomes undefined. Arguments and Return Values Parameters: A variable containing the change in y and another containing the change in x of any numeric data type or organization. Return Value: An array of type double and organization of the inputs containing the arctan of the inputs.
