Generates beta distribution probability density function values at specified locations.

Syntax

PDF = BetaPDF(Points, a, b)

Arguments

Name

Description

Points

A scalar, vector, or matrix of points where the density function is to be evaluated. The output is 0 outside of the interval [0, 1].

a

First shape parameter. A positive scalar.

b

Second shape parameter. A positive scalar.

Outputs

Name

Description

PDF

A scalar, vector, or matrix of the density function values at the given points. The same size as Points.

Example

Find the beta probability density function at points 0.1, 0.3, and 0.8 with parameters a = 2 and b = 5.

Syntax

pdf = BetaPDF([0.1,0.3,0.8],2,5)
