Calculates the probability density function of the pressure amplitude from a finite number of sine waves of arbitrary individual amplitudes, given in Equation 56 of Barakat 1974, using the terminology of that paper.

Description

Calculates the probability density function of the pressure amplitude from a finite number of sine waves of arbitrary individual amplitudes, given in Equation 56 of Barakat 1974, using the terminology of that paper.

Usage

dBarakatA(
  r,
  beta_n,
  magn = 1,
  N = 100,
  betadistr = c("seq", "flat"),
  max.memory = 1e+09
)

Arguments

r	is the argument (superimposed pressure amplitude).
beta_n	is the vector of individual pressure amplitudes, or a single number giving the number of significant scatterers.
N	is the number of positive roots of the Bessel function of the first kind.
max.memory	is the maximum memory occupied by the function before splitting into a loop for each value of 'r'.
