chi2cdf

Compute chi-squared distribution cumulative distribution function values.

Syntax

p=chi2cdf(x,n)

Inputs

x
Values of the distribution random variable.
Type: double
Dimension: scalar | vector | matrix
n
Degrees of freedom.
Type: integer
Dimension: scalar | vector | matrix

Outputs

p
Cumulative probability values.

Examples

Single value chi2cdf example:

x = 3
n = 5;
p = chi2cdf(x,n);
p = 0.300014
Vector chi2cdf example:
x = [1,2,3,4,5,6,7]
n = 5;
p = chi2cdf(x,n);
p = [Matrix] 1 x 7
