Frost beamformer internal calculations

I'm using the phased.FrostBeamformer object to learn more about wideband adaptive antennas, however, I have several questions about the internals of the calculations. Specifically, using the notation from Frost's paper, I'd like to know how the constraint vector frequencies and values are chosen, and also how the gradient step size, mu, is calculated. These are hidden by the object's interface (only the number of taps need be specified).

Is it possible to see the code internals for the phased.FrostBeamformer object? Is there additional documentation that describes how these items are computed?

Yes, the code is available to see if you do

edit phased.FrostBeamformer

The constraint is simply to return a distortion less signal from the boresight while suppressing the noise covariance. I dont' think the current implementation uses a gradient approach.

HTH and if you have further question, please feel free to contact me directly.

Perfect, thanks for your help!
