Gamma random numbers
generates an array of random numbers from the gamma distribution, where
r
= gamrnd(a
,b
,sz1,...,szN
)sz1,...,szN
indicates the size of each dimension.
gamrnd
is a function specific to the gamma distribution.
Statistics and Machine Learning Toolbox™ also offers the generic function random
, which supports various probability distributions. To use
random
, create a GammaDistribution
probability distribution object and pass the object as an
input argument or specify the probability distribution name and its parameters. Note
that the distribution-specific function gamrnd
is faster than
the generic function random
.
Use randg
to generate random numbers from the
standard gamma distribution (unit scale).
To generate random numbers interactively, use randtool
, a user interface for random number generation.
