Calculates either magnitude, angle, or both of every 2d vector (x(I),y(I)): magnitude(I)=sqrt( x(I)2+y(I)2 ), angle(I)=atan( y(I)/x(I) ) The angles are calculated with ~0.1 degree accuracy. For (0,0) point the angle is set to 0

Parameters

x
Type: System..::..IntPtr
The array of x-coordinates
y
Type: System..::..IntPtr
The array of y-coordinates
magnitude
Type: System..::..IntPtr
The destination array of magnitudes, may be set to IntPtr.Zero if it is not needed
angle
Type: System..::..IntPtr
The destination array of angles, may be set to IntPtr.Zero if it is not needed. The angles are measured in radians (0..2?) or in degrees (0..360?).
