NAME

Math::NumSeq::PlanePathCoord -- sequence of coordinate values from a PlanePath module

SYNOPSIS

 use Math::NumSeq::PlanePathCoord;
 my $seq = Math::NumSeq::PlanePathCoord->new (planepath => 'SquareSpiral',
                                              coordinate_type => 'X');
 my ($i, $value) = $seq->next;

DESCRIPTION

This is a tie-in to present coordinates from a Math::PlanePath module as a NumSeq sequence.

FUNCTIONS

$seq = Math::NumSeq::PlanePathCoord->new (planepath => $name, coordinate_type => 'X')

Create and return a new sequence object. The planepath option is the name of one of the Math::PlanePath modules.

coordinate_type (a string) is what coordinate from the path is wanted. The choices are

    "X"          X coordinate
    "Y"          Y coordinate
    "Sum"        X+Y sum
    "Radius"     sqrt(X^2+Y^2) radius 
    "RSquared"   X^2+Y^2 radius squared

$value = $seq->ith($i)

Return the coordinate at N=$i in the PlanePath.
