atan2

odl.atan2(x1, x2, out=None)

Calculates an implementation-dependent approximation of the inverse tangent of the quotient x1/x2, having domain `[-infinity, +infinity]

imes [-infinity, +infinity]` (where the ` imes` notation denotes the set

of ordered pairs of elements (x1_i, x2_i)) and codomain [-pi, +pi], for each pair of elements (x1_i, x2_i) of the input arrays x1 and x2, respectively.
