NAME

Math::GSL::MatrixComplex - Complex Matrices

SYNOPSIS

use Math::GSL::MatrixComplex qw/:all/;
my $matrix1 = Math::GSL::MatrixComplex->new(5,5);  # OO interface
my $matrix2 = gsl_matrix_complex_alloc(5,5);        # standard interface

Objected Oriented Interface to GSL Math::GSL::MatrixComplex

new()

Creates a new MatrixComplex object of the given size.

my $matrix = Math::GSL::MatrixComplex->new(10,10);

raw()

Get the underlying GSL matrix object created by SWIG, useful for using gsl_matrix_* functions which do not have an OO counterpart.

my $matrix     = Math::GSL::MatrixComplex->new(3,3);
my $gsl_matrix = $matrix->raw;
my $stuff      = gsl_matrix_get($gsl_matrix, 1, 2);

rows()

Returns the number of rows in the matrix.

my $rows = $matrix->rows;

cols()

Returns the number of columns in the matrix.

my $cols = $matrix->cols;

as_list()

Get the contents of a Math::GSL::Matrix object as a Perl list.

my $matrix = Math::GSL::MatrixComplex->new(3,3);
...
my @matrix = $matrix->as_list;

row()

Returns a row matrix of the row you enter.

my $matrix = Math::GSL::MatrixComplex->new(3,3);
...
my $matrix_row = $matrix->row(0);

col()

Returns a col matrix of the column you enter.

my $matrix = Math::GSL::MatrixComplex->new(3,3);
...
my $matrix_col = $matrix->col(0);

set_row()

Sets a the values of a row with the elements of an array.

my $matrix = Math::GSL::MatrixComplex->new(3,3);
$matrix->set_row(0, [8, 6, 2]);

You can also set multiple rows at once with chained calls: my $matrix = Math::GSL::MatrixComplex->new(3,3); $matrix->set_row(0, [8, 6, 2]) ->set_row(1, [2, 4, 1]); ...

set_col()

Sets a the values of a column with the elements of an array.

my $matrix = Math::GSL::MatrixComplex->new(3,3);
$matrix->set_col(0, [8, 6, 2]);

You can also set multiple columns at once with chained calls: my $matrix = Math::GSL::MatrixComplex->new(3,3); $matrix->set_col(0, [8, 6, 2]) ->set_col(1, [2, 4, 1]); ...
