Generates log-normal distribution probability density function values at specified locations.

Syntax

PDF = LogNormPDF(Points, Mean, Std)

Arguments

Name

Description

 

Points

A scalar, vector, or matrix of positive data points at which the density function is to be evaluated.

 

Mean

Mean of the log of the distribution. A scalar.

 

Std

Standard deviation of the log of the distribution. 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 log-normal probability density function at points 1, 4, and 8 with parameters Mu = 2 and sigma = 5.

 

Syntax

 

pdf = LogNormPDF([1,4,8],2,5)
