Math::NumSeq::LucasNumbers -- Lucas numbers
use Math::NumSeq::LucasNumbers; my $seq = Math::NumSeq::LucasNumbers->new; my ($i, $value) = $seq->next;
The Lucas numbers 1, 3, 4, 7, 11, 18, 29, etc, being L(i) = L(i-1) + L(i-2) starting from 1,3. This is the same recurrence as the Fibonacci numbers, but a different starting point.
See "FUNCTIONS" in Math::NumSeq for the behaviour common to all path classes.
$seq = Math::NumSeq::LucasNumbers->new ()
Create and return a new sequence object.
$value = $seq->ith($i)
$i'th Lucas number.
$bool = $seq->pred($value)
Return true if
$valueis a Lucas number.
