NAME

CXC::Number::Sequence - Numerical Sequence Generation

VERSION

version 0.13

SYNOPSIS

use CXC::Number::Sequence;

CXC::Number::Sequence->build( $type, %options );

DESCRIPTION

This is an entry point for building sequences of numbers.

WARNING

Currently, a sequence is a subclass of CXC::Number::Sequence, but this may change to a role based relationship.

Constraints

At present sequences are not lazily built. This can easily be accommodated and iterators added.

CONSTRUCTORS

build

$sequence = CXC::Number::Sequence->build( $class, %options );

Construct a sequence of type $class, where $class is a subclass of CXC::Number::Sequence. If $class is in the CXC::Number::Sequence namespace, only the relative class name is required, e.g.

linear => CXC::Number::Sequence::Linear

(note that $class is converted to CamelCase; input words should be separated by a _).

build will first attempt to load $class in the CXC::Number::Sequence namespace, and if not present will assume $class is a full package name.

METHODS

elements

$array_ref = $sequence->elements;

Return the sequence elements as a reference to an array of Perl numbers.

nelem

$nelem = $sequence->nelem;

The number of elements in the sequence.

spacing

$spacing = $sequence->spacing;

Return the spacing between elements as a reference to an array of Perl numbers.

min

$min = $sequence->min;

Returns the minimum bound of the sequence as a Perl number.

max

$max = $sequence->max;

Returns the maximum bound of the sequence as a Perl number.

bignum

$elements = $sequence->bignum->elements;

Returns an object which returns copies of the internal Math::BigFloat objects for the following methods

elements -> Array[Math::BigFloat]
spacing  -> Array[Math::BigFloat]
min      -> Math::BigFloat
max      -> Math::BigFloat

pdl

$elements = $sequence->pdl->elements;

Returns an object which returns piddles for the following methods

elements -> piddle
spacing  -> piddle
