Function Reference: nakapdf

statistics: y = nakapdf (x, mu, omega)

Nakagami probability density function (PDF).

For each element of x, compute the probability density function (PDF) of the Nakagami distribution with shape parameter mu and spread parameter omega. The size of y is the common size of x, mu, and omega. A scalar input functions as a constant matrix of the same size as the other inputs.

Both parameters must be positive reals and mu >= 0.5. For mu < 0.5 or omega <= 0, NaN is returned.
