Finding half power beamwidth and first null beamwith for phased.ConformalArray

Hi Team

I have made a phased.ConformalArray, I am able to get the magnitude values corresponding to each azimuth and elevation angles. I would like to find the half power beamwith, first null beamwidth for the array. I would also like to get the [azimuth,elevation] at each of the -3dB points, and also the [mag,az_angle,el_angle] for the first n nulls and sidelobes(peaks).

PFA the m-file.

Thanks and Regards
