I am trying to understand the functionality of angle function of matlab. I am trying to convert my matlab code(which we use for proof of concept) to C++ implementation.
input to angle function - 0.487936206701072 + 0.660466136142335i
output of angle function - 0.934517679414299
I know it must be tan-inverse(img/real) with some other constant.
Please help me with the formula?

It's all written in the MATLAB documentation of "angle":
angle takes a complex number z = x + iy and uses the atan2 function to compute the angle between the positive x-axis and a ray from the origin to the point (x,y) in the xy-plane.
Here is the "proof":
z = 0.487936206701072 + 0.660466136142335*1i;
