Generates chi squared distribution cumulative density function values at specified locations.

Syntax

CDF = Chi2CDF(Points, n)

Arguments

Name

Description

 

Points

A scalar, vector, or matrix of positive data points at which the cumulative density function is to be evaluated. The output is 0 for negative values.

 

n

Degrees of freedom parameter. A positive integer.

Outputs
