I am tyring to understand the output from resp in the phased.CustomAntennaElement toolbox
The code is as follows:
myant= phased.CustomAntennaElement('AzimuthAngles',az, ...
'ElevationAngles',el,'RadiationPattern',pat_azel);
az, el is -90:90 and -180:180, pat_azel is the custom pattern 181x361
ang = [0 180];
resp = step(myant,fc,ang) gives 2 numbers ?
From the documentation thus far, ang is the value at az=0 elevation=180
so resp should only have a single value, I check the orginal output and it
is in dB mag. and not a vector. I followed this from the custom antenna element example.
Any feedback is welcome, thanks.
Regards, Philip

Hi Philip,
When you pass in ang = [0 180], it is considered as two angles, az = 0 and az = 180. if you pass in ang = [0;180], then it is one angle pointing at az = 0 and el = 180.
