Function Reference: riceinv

statistics: x = riceinv (p, s, sigma)

Inverse of the Rician distribution (iCDF).

For each element of p, compute the quantile (the inverse of the CDF) of the Rician distribution with non-centrality (distance) parameter s and scale parameter sigma. The size of x is the common size of x, s, and sigma. A scalar input functions as a constant matrix of the same size as the other inputs.

Further information about the Rician distribution can be found at https://en.wikipedia.org/wiki/Rice_distribution
