Subject: [Perldl] [ANN] PDL::FuncND
I've just released PDL::FuncND to CPAN. It provides multi-dimensional
versions of functions which can be evaluated either at discrete points
or on grids.
At some point I'd like to transition this into PDL proper, but I've run
out of tuits at the moment.
It currently provides the following functions:
* gaussND
* cauchyND
* lorentzND
* mahalonobis
https://metacpan.org/module/PDL::FuncND
Just gave it a try on MS Windows (perl-5.16.0).
I'm getting a failure in t/cauchyND.t :
####################################
C:\sisyphusion\PDL-FuncND-0.06>perl -Mblib t/cauchyND.t
1..8
ok 1 - use PDL::FuncND;
Undefined subroutine &PDL::FuncND::lgamma called at
C:\sisyphusion\PDL-FuncND-0.06\blib\lib/PDL/FuncND.pm line 345, <DATA> line
206.
# Looks like you planned 8 tests but ran 1.
# Looks like your test exited with 255 just after 1.
####################################
Line 345 of FuncND.pm is:
sub _gamma { exp( (lgamma(@_))[0]) }
From where do you pick up the lgamma() implementation ?
(No other issues, btw.)
Cheers,
Rob
