/**
|
|
* Calculate the inverse tangent function with two arguments, y/x.
|
|
* By providing two arguments, the right quadrant of the computed angle can be
|
|
* determined.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.atan2(y, x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.atan2(2, 2) / math.pi // returns number 0.25
|
|
*
|
|
* const angle = math.unit(60, 'deg') // returns Unit 60 deg
|
|
* const x = math.cos(angle)
|
|
* const y = math.sin(angle)
|
|
*
|
|
* math.atan(2) // returns Complex 1.5707963267948966 -1.3169578969248166 i
|
|
*
|
|
* See also:
