Generates beta distribution cumulative density function values at specified locations.

Syntax

CDF = BetaCDF(Points, a, b)

Arguments

Name

Description

Points

A scalar, vector, or matrix of points where the cumulative density function is to be evaluated. The output is zero to the left of 0 and one to the right of 1.

a

First shape parameter. A positive scalar.

b

Second shape parameter. A positive scalar.

Outputs

Name

Description

CDF

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

Example

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

Syntax

cdf = BetaCDF([0.1,0.3,0.8],2,5)

Results

cdf = 0.11427     0.57983     0.9984
