NAME
Math::GSL::VectorComplex - Complex Vectors
SYNOPSIS
use Math::GSL::VectorComplex qw/:all/;
my $vec1 = Math::GSL::VectorComplex->new([1 + 2*i, 7*i, 5, -3 ]);
my $vec2 = $vec1 * 5;
my $vec3 = Math::GSL::Vector>new(10); # 10 element zero vector
my $vec4 = $vec1 + $vec2;
# set the element at index 1 to -i
# and the element at index 3 to i
$vec3->set([ 1, -i ], [ 9, i ]);
my @vec = $vec2->as_list; # return elements as Perl list
my $dot_product = $vec1 * $vec2;
my $length = $vec2->length;
my $first = $vec1->get(0);Objected Oriented Interface to GSL Math::GSL::VectorComplex
new()
Creates a new Vector of the given size.
my $vector = Math::GSL::VectorComplex->new(3);You can also create and set directly the values of the vector like this :
my $vector = Math::GSL::VectorComplex->new([2,4,1]);raw()
Get the underlying GSL vector object created by SWIG, useful for using gsl_vector_* functions which do not have an OO counterpart.
my $vector = Math::GSL::VectorComplex->new(3);
my $gsl_vector = $vector->raw;
my $stuff = gsl_vector_get($gsl_vector, 1);min()
Returns the minimum value contained in the vector.
my $vector = Math::GSL::VectorComplex->new([2,4,1]);
my $minimum = $vector->min;max()
Returns the minimum value contained in the vector.
my $vector = Math::GSL::VectorComplex->new([2,4,1]);
my $maximum = $vector->max;length()
Returns the number of elements contained in the vector.
my $vector = Math::GSL::VectorComplex->new([2,4,1]);
my $length = $vector->length;as_list()
Gets the content of a Math::GSL::Vector object as a Perl list.
my $vector = Math::GSL::VectorComplex->new(3);
...
my @values = $vector->as_list;get()
Gets the value of an of a Math::GSL::Vector object.
my $vector = Math::GSL::VectorComplex->new(3);
...
my @values = $vector->get(2);You can also enter an array of indices to receive their corresponding values:
my $vector = Math::GSL::VectorComplex->new(3);
...
my @values = $vector->get([0,2]);reverse()
Returns the a vector with the elements in reversed order.
use Math::Complex;
my $v1 = Math::GSL::VectorComplex->new([ 1, 2, 3*i]);
my $v2 = $v1->reverse;set()
Sets values of an of a Math::GSL::Vector object.
my $vector = Math::GSL::VectorComplex->new(3);
$vector->set([1,2], [8,23]);This sets the second and third value to 8 and 23.
copy()
Returns a copy of the vector, which has the same length and values but resides at a different location in memory.
my $vector = Math::GSL::VectorComplex->new([10 .. 20]);
my $copy = $vector->copy;swap()
Exchanges the values in the vectors $v with $w by copying.
my $v = Math::GSL::VectorComplex->new([1..5]);
my $w = Math::GSL::VectorComplex->new([3..7]);
$v->swap( $w );AUTHORS
