Statistics and Machine Learning Toolbox™ offers several ways to work with the lognormal distribution.
Create a probability distribution object LognormalDistribution
by fitting a probability distribution to sample data or by
specifying parameter values. Then, use object functions to
evaluate the distribution, generate random numbers, and so
on.
Work with the lognormal distribution interactively by using the Distribution Fitter app. You can export an object from the app and use the object functions.
Use distribution-specific functions with specified distribution parameters. The distribution-specific functions can accept parameters of multiple lognormal distributions.
Use generic distribution functions (cdf
, icdf
, pdf
, random
) with a
specified distribution name ('Lognormal'
) and
parameters.
To learn about the lognormal distribution, see Lognormal Distribution.

The lognormal distribution is a probability distribution whose logarithm has a normal distribution.
