It then reads numbers from `stdin', +one line at a time, and adds them to the histogram. When there is no +more data to read it prints out the accumulated histogram using +gsl_histogram_fprintf. If n is unspecified then bins of integer width +are used. +.SH EXAMPLE +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 + +.SH SEE ALSO +.BR gsl(3) , +.BR gsl-randist(1) . + +.SH AUTHOR +.B gsl-histogram +was written by Brian Gough. +Copyright 1996-2000; for copying conditions see the GNU General +Public Licence. + +This manual page was added by the Dirk Eddelbuettel +<edd@debian.org>, the Debian GNU/Linux maintainer for +.BR GSL . |
