I have 2 machines on different versions of PDL and GSL.
Both are pre-packed Ubuntu versions.
The older one supports PDL::GSL::INTERP with {Extrapolate => 1}
The somewhat newer one doesn't. Is this known behavior ?
I modified the example code to ask for an extrapolated version.
===code
use PDL;
use PDL::GSL::INTERP;
my $x = sequence(10);
my $y = exp($x);
my $spl = PDL::GSL::INTERP->init('cspline',$x,$y);
my $res = $spl->eval(14.35,{Extrapolate => 1});
print $res."\n";
=== result1
PDL v2.4.5 (supports bad values)
-81198.810683691
=== result2
PDL v2.4.7_001 (supports bad values)
./tstipol.pl
gsl: interp.c:150: ERROR: interpolation error
