Hello,

I am using this code for experiments for other synthetic data where data is generated by matlab , I see that estimations are totally wrong when the (x, y) both are negative which means the when phi is 180 to 270. Can you please let me know if you have any idea ?

Regards Bheeshma

The angle has to be normalized between -pi and pi. Therefore, it will neither work in the 3rd nor 4th quadrant.
