=head1 Objected Oriented Interface to GSL Math::GSL::VectorComplex

=head2 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]);

=cut

sub new {
    my ($class, $values) = @_;
    my $length  = $#$values;
    my $this = {};
    my $vector;

    # we expect $values to have Math::Complex objects
    @$values = map { gsl_complex_rect(Re($_), Im($_)) } @$values;

    if ( ref $values eq 'ARRAY' ){
        die __PACKAGE__.'::new($x) - $x must be a nonempty array reference' if $length == -1;
        $vector  = gsl_vector_complex_alloc($length+1);
        map { gsl_vector_complex_set($vector, $_, $values->[$_] ) }  (0 .. $length);
        $this->{_length} = $length+1;
    } elsif ( (int($values) == $values) && ($values > 0)) {
        $vector  = gsl_vector_complex_alloc($values);
        gsl_vector_complex_set_zero($vector);
        $this->{_length} = $values;
    } else {
        die __PACKAGE__.'::new($x) - $x must be an int or array reference';
    }
    $this->{_vector} = $vector;
    bless $this, $class;
}


=head2 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);

=cut

sub raw { 
    my $self = shift;
    return $self->{_vector};
}

=head2 min()

Returns the minimum value contained in the vector.

   my $vector = Math::GSL::VectorComplex->new([2,4,1]);
   my $minimum = $vector->min;

=cut 

sub min {
    my $self=shift;
    return gsl_vector_min($self->raw);
}

=head2 max()

Returns the minimum value contained in the vector.

   my $vector = Math::GSL::VectorComplex->new([2,4,1]);
   my $maximum = $vector->max;

=cut 

sub max {
    my $self=shift;
    return gsl_vector_max($self->raw);
}

=head2 length()

Returns the number of elements contained in the vector.

   my $vector = Math::GSL::VectorComplex->new([2,4,1]);
   my $length = $vector->length;

=cut 

sub length { my $self=shift; $self->{_length} }

=head2  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;
=cut

sub as_list {
    my $self=shift;
    # this is wrong
    return map { cplxe( gsl_complex_abs($_), gsl_complex_arg($_) ) } $self->get( [ 0 .. $self->length - 1  ] );
}

=head2  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]);

=cut

sub get {
    my ($self, $indices) = @_;
    return  map {  gsl_vector_complex_get($self->raw, $_ ) } @$indices ;
}

=head2 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;

=cut

sub reverse {
    my $self = shift;
    my $copy = $self->copy();
    unless ( is_status_ok( gsl_vector_complex_reverse( $copy->raw )) ) {
        die( __PACKAGE__.": error reversing vector " . gsl_strerror($status) );
    }
    return $copy;
}

=head2  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.

=cut

sub set {
    my ($self, $indices, $values) = @_;
    die (__PACKAGE__.'::set($indices, $values) - $indices and $values must be array references of the same length')
        unless ( ref $indices eq 'ARRAY' && ref $values eq 'ARRAY' &&  $#$indices == $#$values );
    eval {
        map {  gsl_vector_complex_set($self->{_vector}, $indices->[$_], $values->[$_] ) } (0..$#$indices);
    };
    # better error handling?
    warn $@ if $@;
    return;
}

=head2 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;

=cut

    my $self = shift;

    }
    return $copy;
}

=head2 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 );

=cut
