| Description | Argi = arctan( Im(Xi) / Re(Xi) )
The argument, i.e. the angle of each element of the complex vector X is calculated. For Cartesian coordinates {0, 0}, the angle is arbitrary and is set to zero.
When necessary, depending on the signs of Re(Xi) and Im(Xi), p is added or subtracted from the arctan to obtain the correct quadrant. |
