gsl_ran_landau_pdf

[mtrocme]

Hi there,

I'm trying to integrate the function 'gsl_ran_landau_pdf'
https://www.gnu.org/software/gsl/manual/html_node/The-Landau-Distribution.html
to octave using the octave-gsl wrapper
https://sourceforge.net/p/octave/gsl/ci/1.0.8/tree/src/README
since this function is not (yet) available :
https://www.gnu.org/software/octave/doc/interpreter/Random-Number-Generation.html#Random-Number-Generation
https://octave.sourceforge.io/gsl/overview.html

I managed to successfully install octave-gsl using the following set of
commands :
# sudo apt-get install mercurial autoconf liboctave-dev
# hg clone http://hg.code.sf.net/p/octave/gsl octave-gsl
# cd octave-gsl/src/
# ./bootstrap && ./configure && make
# cd .. && make install

I also managed to add the 'gsl_ran_landau_pdf' function without any
compilation error
# ./bootstrap && ./configure && make && cd .. && sudo \rm -rf
/home/user/octave/gsl-2.0.0 && make install
## checking for gsl_ran_landau_pdf... yes
adding the following lines to the end of the file 'src/buildgsl_sf.sh'
#  export octave_name=gsl_sf_ran_landau_pdf
#  export    funcname=gsl_ran_landau_pdf
#  cat << \EOF > docstring.txt
#  This function computes the probability density p(x) at x for the Landau
distribution.
#  See
https://www.gnu.org/software/gsl/manual/html_node/The-Landau-Distribution.html
#  EOF
#  ${RT} D_DD >> gsl_sf.cc

However I don't see the 'gsl_sf_ran_landau_pdf' function in octave :
# Octave
# >> pkg load gsl
# >> gsl_sf_ <TAB>

Could you please tell me what I'm missing ?

Thanks for your time and consideration,
Mathieu
