gsl-randist - generate random samples from various distributions
gsl-randist seed n DIST param1 param2 [..]
gsl-randist is a demonstration program for the GNU Scientific Library. It generates n random samples from the distribution DIST using the distribution parameters param1, param2, ...
Here is an example. We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range -100 to 100, using 200 bins.
gsl-randist 0 10000 cauchy 30 | gsl-histogram -- -100 100 200 >
histogram.dat
A plot of the resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample size.
awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X
