NAME
Physics::Lorentz::Vector - Representation of 4-vectors
SYNOPSIS
use Physics::Lorentz;
my $rotation = Physics::Lorentz::Transformation->rotation_euler(
$alpha, $beta, $gamma
);
my $vector = Physics::Lorentz::Vector->new([$t, $x, $y, $z]);
my $rotated = $rotation->apply($vector);
# or: $rotated = $rotation * $vector;
...DESCRIPTION
This class is a representation of 4-vectors (such as 4-space [time, x, y, z] or 4-momentum E, kx, ky, kz).
EXPORT
None.
OVERLOADED INTERFACE
Addition (+) does the expected thing as does the assignment form (+=) of it.
Stringification is overloaded with the stringify method.
See also: Physics::Lorentz::Transformation.
METHODS
new
Creates a new Physics::Lorentz::Vector object. Defaults to [0,0,0,0] or cloning if no arguments are specified.
If one argument is present, this argument may either be a PDL which will be used internally as the PDL representation of the vector or an array reference to an array of four elements.
clone
Returns a copy of the object.
stringify
Returns a string representation of the object. Currently, this is the string representation of the internal PDL vector/matrix.
add
Adds two vectors. Syntax:
$v3 = $v1->add($v2);(This leaves $v1 and $v2 unchanged!)
get_pdl
Returns the PDL representation of the object. This is the actual PDL object used inside. Beware of action at a distance.
