Subject: Re: [Bug-gsl] Issue with log1p
Hi Brian,
But in many files where log1p is used, the gsl_sys.h header (where
gsl_log1p
is declared) is not included so the compiler doesn't pick up the
declaration
of gsl_log1p and hence wrongly concludes that it returns an int.
So the header gsl_sys.h needs to be included in all files where log_1p is
used.
Can you confirm that these are the relevant files?
specfunc/beta_inc.c
specfunc/legendre_poly.c
specfunc/gsl_sf_log.h
specfunc/trig.c
specfunc/beta.c
specfunc/gamma_inc.c
specfunc/test_sf.c
specfunc/poch.c
specfunc/log.c
=====================================
Hi Rhys,
The ones I found for log1p are:
cdf\exponentialinv.c
cdf\gammainv.c
cdf\geometric.c
cdf\gumbel1inv.c
cdf\gumbel2inv.c
cdf\paretoinv.c
cdf\rayleighinv.c
cdf\tdist.c
cdf\weibullinv.c
complex\math.c
randist\beta.c
randist\binomial.c
randist\exponential.c
randist\nbinomial.c
specfunc\erfc.c
specfunc\hyperg_1F1.c
sys\invhyp.c
sys\log1p.c
but I have since discovered that some of these are not necessary because
other headers sometimes include the gsl_sys.h header.
==============================
This also applies to other functions that seek to substitute for missing
'standard' functions.
Have a list of functions I might check or a list of files for which
you suggest the gsl_sys.h header be included?
==============================
I made changes to:
cdf\exponential.c
cdf\exponentialinv.c
cdf\gammainv.c
cdf\geometric.c
cdf\gumbel1.c
cdf\gumbel1inv.c
cdf\gumbel2.c
cdf\paretoinv.c
cdf\rayleigh.c
cdf\rayleighinv.c
cdf\tdist.c
cdf\tdistinv.c
cdf\weibull.c
cdf\weibullinv.c
complex\math.c
eigen\francis.c
eigen\genv.c
eigen\herm.c
eigen\hermv.c
eigen\nonsymmv.c
eigen\symm.c
eigen\symmv.c
ieee-utils\env.c
integration\cquad.c
linalg\balance.c
multimin\simplex.c
multimin\simplex2.c
multiroots\dnewton.c
ode-initval2\test.c
poly\solve_cubic.c
randist\beta.c
randist\exponential.c
randist\nbinomial.c
rng\ranf.c
roots\newton.c
roots\secant.c
roots\steffenson.c
specfunc\elljac.c
specfunc\erfc.c
specfunc\hyperg_1F1.c
specfunc\hyperg_U.c
specfunc\legendre_con.c
specfunc\legendre_Qn.c
specfunc\trig.c
sys\expm1.c
sys\hypot.c
sys\invhyp.c
sys\ldfrexp.c
But again, a lot of these might not be necessary as gsl_sys.h is included in
the gsl_math.h (and maybe other) headers
I really need to print out the full header hierarchy to work this out.
This now leaves me with a single failure to converge in both the cdf and
poly tests and two hypergeometric function failures.
