NAME

   Test2::Tools::PDL - Test2 tools for verifying Perl Data Language
   piddles

VERSION

   version 0.0004

SYNOPSIS

       use Test2::Tools::PDL;

       # Functions are exported by default.

       # Ensure something is a piddle.
       pdl_ok($x);

       # Compare two piddles.
       pdl_is($got, $expected, 'Same piddle.');

FUNCTIONS

pdl_ok($thing, $name)

   Checks that the given $thing is a PDL object.

pdl_is($got, $exp, $name);

   Checks that piddle $got is same as $exp.

   Now this method is internally similar as is($got->unpdl, $exp->unpdl).
   It's possible to work with both numeric PDLs as well as non-numeric
   PDLs (like PDL::Char, PDL::SV).

DESCRIPTION

   This module contains tools for verifying PDL piddles.

VARIABLES

   This module can be configured by some module variables.

TOLERANCE, TOLERANCE_REL

   These two variables are used when comparing float piddles. For
   pdl_is($got, $exp, ...), the effective tolerance is $TOLERANCE +
   abs($TOLERANCE_REL * $exp).

   Default value of $TOLERANCE is same as
   $Test2::Compare::Float::DEFAULT_TOLERANCE, which is 1e-8. Default value
   of $TOLERANCE_REL is 0.

   For example, to use only relative tolerance,

       {
           local $Test2::Tools::PDL::TOLERANCE = 0;
           local $Test2::Tools::PDL::TOLERANCE_REL = 1e-6;
           ...
       }
