NAME
Math::Shape::Vector - A 2d vector object in cartesian space
VERSION
version 0.03
SYNOPSIS
use Math::Shape::Vector;
my $v1 = Math::Shape::Vector->new(3, 5);
my $v2 = Math::Shape::Vector->new(1, 17);
$v1->add_vector($v2);
$v1->negate;
$v1->multiply(5);
$v1->is_equal($v2);
METHODS
new
Create a new vector. Requires two numerical arguments for the origin and magnitude.
my $vector = Math::Shape::Vector->new(3, 5);add_vector
Adds a vector to the vector object, updating its x & y values.
$vector->add_vector($vector_2);subtract_vector
Subtracts a vector from the vector object, updating its x & y values.
$vector->subtract_vector($vector_2);negate
Negates the vector's values e.g. (1,3) becomes (-1, -3).
$vector->negate();is_equal
Compares a vector to the vector object, returning 1 if they are the same or 0 if they are different.
$vector->is_equal($vector_2);multiply
Multiplies the vector's x and y values by a number.
$vector->multiply(3);divide
Divides the vector's x and y values by a number.
$vector->divide(2);get_length
Returns the vector length.
