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 );
