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

Example: 1

Plot various iCDFs from the Rician distribution

 p = 0.001:0.001:0.999;
 x1 = riceinv (p, 0, 1);
 x2 = riceinv (p, 0.5, 1);
 x3 = riceinv (p, 1, 1);
 x4 = riceinv (p, 2, 1);
 x5 = riceinv (p, 4, 1);
 plot (p, x1, '-b', p, x2, '-g', p, x3, '-r', p, x4, '-m', p, x5, '-k')
