/**
* 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 number 1.1071487177940904
*
* See also:
*
* tan, atan, sin, cos
*
* @param {number | Array | Matrix} y Second dimension
* @param {number | Array | Matrix} x First dimension
* @return {number | Array | Matrix} Four-quadrant inverse tangent
