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?
