DESCRIPTION

OPERATORS

Summary

'!'		=>   Returns true if the length of this vector is 0

'<'		=>   Numerical gt. Compares the length of this vector with a vector or a scalar value.
'<='		=>   Numerical le. Compares the length of this vector with a vector or a scalar value.
'>'		=>   Numerical lt. Compares the length of this vector with a vector or a scalar value.
'>='		=>   Numerical ge. Compares the length of this vector with a vector or a scalar value.
'<=>'		=>   Numerical cmp. Compares the length of this vector with a vector or a scalar value.
'=='		=>   Numerical eq. Performs a componentwise equation.
'!='		=>   Numerical ne. Performs a componentwise equation.

'lt'		=>   Stringwise lt
'le'		=>   Stringwise le
'gt'		=>   Stringwise gt
'ge'		=>   Stringwise ge
'cmp'		=>   Stringwise cmp
'eq'		=>   Stringwise eq
'ne'		=>   Stringwise ne

'int'		=>   Performs a componentwise int.

'abs'		=>   Performs a componentwise abs.

'""'		=>   Returns a string representation of the vector.

METHODS

new

my $b = new Math::VecX; 					  
my $c = new Math::VecX(1,2, @a);
my @d = @$c;

If you call new() with a reference to an array, it is used as reference internally.

my $f = new Math::VecX([1,2, @a]);

copy

Makes a copy

$c = $v->copy;

getValue

Returns the value of the vector as array.

@v = $v1->getValue;

setValue(x,y,z)

Sets the value of the vector

$v1->setValue(1,2);

rotate(steps)

Performs a componentwise rotation. A positiv number performs a clockwise rotation. A negativ number performs a counter-clockwise rotation.

$v = $vec->rotate(1);
$v = $vec->rotate(2);

sig

Performs a componentwise sig.

$v = new Math::VecX(-4, 5);
$v = $VecX->sig;
printf $v;         # -1 1

sum

Returns the sum of the components.

$v = new Math::VecX(-8, 2);
$s = $VecX->sum;
printf $s;         # -6

normalize

$v = $v1->normalize;

toString

Returns a string representation of the vector. This is used to overload the '""' operator, so that vector may be freely interpolated in strings.

my $q = new Math::VecX(1,2);
print $q->toString;                # "1 2"
print "$q";                        # "1 2"
