Thanks for maintaining gsl; I use it all the time.

The gsl-randist(1) page suggest the sample command

            gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200

which has a typo: gsl-histogram interprets the -100 as an option. It should read

            gsl-randist 0 10000 cauchy 30 | gsl-histogram -- -100 100
200 > histogram.dat

or even

            gsl-randist 0 100000 cauchy 30 | gsl-histogram -- -100 100
200 | awk '{print $1, $3 ; print $2, $3}' | graph -T X

Cheers,

My pleasure, and "anytime" -- I get a lot of use out of your packaging too :)

Thanks -- seems plainly upstream. I have another issue for them (they named a
struct element 'class' or something like that upsetting C++ use) and maybe
Patrick can fix that for the next release.

Cheers, Dirk

Great, thanks.

If they're open to suggestions for more examples, I use the below when
teaching matrix decomposition methods (Principle Components Analysis,
Independent Components Analysis, Nonnegative Matrix Factorization) in
Machine Learning. It's way more fun to actually see something
calculated from scratch, and be able to fiddle with it and get an
intuition, than to just see a canned figure.

paste <(gsl-randist 0 30000 exppow 1 2)  <(gsl-randist 1 30000 exppow
1 2) | awk '{print $1+0.8*$2, $2+0.3*$1}' |graph -T X --line-mode 0
--bitmap-size 1024x1024

paste <(gsl-randist 0 30000 exppow 1 0.7)  <(gsl-randist 1 30000
exppow 1 0.7) | awk '{print $1+0.8*$2, $2+0.3*$1}' |graph -T X
--line-mode 0 --bitmap-size 1024x1024

paste <(gsl-randist 0 30000 exppow 1 8)  <(gsl-randist 1 30000 exppow
1 8) | awk '{print $1+0.8*$2, $2+0.3*$1}' |graph -T X --line-mode 0

Sorry, took a moment but this is now applied -- and had been reported upstream.

Thanks again,  Dirk
