Statistics and Machine Learning Toolbox™ offers several ways to work with the Weibull distribution.
Create a probability distribution object WeibullDistribution
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 Weibull 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 Weibull distributions.
Use generic distribution functions (cdf
, icdf
, pdf
, random
) with a
specified distribution name ('Weibull'
) and
parameters.
To learn about the Weibull distribution, see Weibull Distribution.

The Weibull pdf is an appropriate analytical tool for modeling the breaking strength of materials. Current usage also includes reliability and lifetime modeling.
