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

The exponential distribution is special because of its utility in modeling events that occur randomly over time. The main application area is in studies of lifetimes.
