The Exponential Distribution
Random:
double
gsl_ran_exponential
(const gsl_rng *
r
, double
mu
)
This function returns a random variate from the exponential distribution with mean
mu
. The distribution is,
p(x) dx = {1 \over \mu} \exp(-x/\mu) dx
for x >= 0.
Function:
double
gsl_ran_exponential_pdf
(double
x
, double
mu
)
This function computes the probability density p(x) at
x
for an exponential distribution with mean
mu
, using the formula given above.
