chi2pdf

Compute chi-squared distribution probability density function values.

Syntax

d=chi2pdf(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

d
Probability density values.

Examples

Single value chi2pdf example:
x = 3;
n = 5;
d = chi2pdf(x,n)
d = 0.15418
Vector chi2pdf example:
x = [1:1:7];
n = 5;
d = chi2pdf(x,n)
d = [Matrix] 1 x 7
