NAME

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

VERSION

version 0.0001

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

TOLERANCE

Default is same as $Test2::Compare::Float::DEFAULT_TOLERANCE, which is 1e-8.

$Test2::Tools::PDL::TOLERANCE = 0.01;
