ricecdf
"upper"
)Rician cumulative distribution function (CDF).
For each element of x, compute the cumulative distribution function (CDF) of the Rician distribution with non-centrality (distance) parameter nu and scale parameter sigma. The size of p is the common size of x, nu, and sigma. A scalar input functions as a constant matrix of the same size as the other inputs.
p = ricecdf (x, nu, sigma, "upper")
computes
the upper tail probability of the Rician distribution with parameters
nu and sigma, at the values in x.
