StatsVonMisesPDF

StatsVonMisesPDF (θ, a, b)

The StatsVonMisesPDF function returns the von Mises probability distribution function

$$\displaystyle f(\theta ; a, b)=\frac{\exp (b \cos (\theta-a))}{2 \pi I_{0}(b)} .$$

where I₀(b ) is the modified Bessel function of the first kind bessI, and 0<θ<=2π, 0<a <=2π, and b >0.
