NAME
Math::NumSeq::Perrin  Perrin sequence
SYNOPSIS
use Math::NumSeq::Perrin;
my $seq = Math::NumSeq::Perrin>new;
my ($i, $value) = $seq>next;
DESCRIPTION
The Perrin sequence,
3, 0, 2, 3, 2, 5, 5, 7, 10, 12, 17, 22, 29, 39, 51, etc
which is the recurrence
P(i) = P(i2) + P(i3)
starting from 3,0,2. So for example 29 is 12+17.
12, 17, 22, 29

FUNCTIONS
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.

$value = $seq>ith($i)

Return the
$i
'th value from the sequence. $i = $seq>value_to_i_estimate($value)

Return an estimate of the i corresponding to
$value
.
