A general-purpose function that calculates the PDF of the homodyned-k distribution over the input range xdata defined by the following parameters:
x(1) = alpha, effective mean number of scatterers
x(2) = s, envelope of the coherent signal
x(3) = sigma, mean energy of the noncoherent scatterers

Version Published Release Notes
1.2.0.0

In the previous version, the model output varied with input range of gamma distribution. This is a more robust model which does not depend on gamma distribution. Tradeoff is greater analytical complexity (high number of summation terms)
