| jpayne@68 | 4 .SH NAME |
| jpayne@68 | 5 gsl-randist - generate random samples from various distributions |
| jpayne@68 | 6 .SH SYNOPSYS |

| jpayne@68 | 8 .SH DESCRIPTION |
| jpayne@68 | 9 .B gsl-randist |
| jpayne@68 | 10 is a demonstration program for the GNU Scientific Library. |
| jpayne@68 | 11 It generates n random samples from the distribution DIST using the distribution |
| jpayne@68 | 12 parameters param1, param2, ... |
| jpayne@68 | 13 .SH EXAMPLE |
| jpayne@68 | 14 Here is an example. We generate 10000 random samples from a Cauchy |
| jpayne@68 | 15 distribution with a width of 30 and histogram them over the range -100 to |
| jpayne@68 | 16 100, using 200 bins. |

| jpayne@68 | 19 |
| jpayne@68 | 20 A plot of the resulting histogram will show the familiar shape of the |
| jpayne@68 | 21 Cauchy distribution with fluctuations caused by the finite sample |
| jpayne@68 | 22 size. |
