This module implements various constructors and methods for creating and manipulating matrices. All methods return new objects, so, for example, "$X->add($Y)" does not modify $X. $X -> add($Y); # $X not modified; output is lost $X = $X -> add($Y); # ...

This module is part of the Math::GSL distribution. It defines a Perl insterface to GNU Scientific Library matrices. There are two different (but not exclusive) ways to use this module: using the OO API, built manually over the GSL functions, or using...

This is a classic matrix. It has a size and makes sure all elements conform to it. Currently it doesn't do very much except help you forget about how to actually store the values. You can store values of whatever type you want in this matrix....

This module is a layer on top of the basic routines in the cephes math library for operations on square matrices. In the following, a Math::Cephes::Matrix object is created as my $M = Math::Cephes::Matrix->new($arr_ref); where $arr_ref is a reference...

A banded matrix (or band matrix or band diagonal matrix) is a matrix whose non-zero columns are confined to a diagonal band. Obviously, such a structure allows for more efficient storage and computation than for a general matrix. CAVEAT: This is a yo...

This is a bundle of modules related to math with matrices or vectors. Please have a look at Bundle::Math. If you would like to see a specific module included in a future version of this bundle, please send me an email or use rt.cpan.org....

This module provides basic functionality for handling matrices of Galois Field elements. It is a fairly "close to the metal" implementation using the C language to store the underlying object and handle performance-critical tasks such as bulk input/o...

This module interfaces with "Math::GSL::Matrix" or, if that is not available, "Math::MatrixReal". The idea behind this module is to allow the development of tools that use matrices that will work in pure Perl (using "Math::MatrixReal") or with extra ...

The following methods are available: new Constructor arguments are a list of references to arrays of the same length. The arrays are copied. The method returns undef in case of error. $a = new Math::Matrix ([rand,rand,rand], [rand,rand,rand], [rand,r...

This class lets you dynamically create boolean matrices of arbitrary size and perform all the basic operations for matrices on them, like - setting or deleting elements, - testing wether a certain element is set, - computing the sum, difference, prod...

Math::SparseMatrix provides simple sparse matrix functionality such as creation of sparse matrices, writing them out to a file, reading matrices from files and reading transpose of a matrix stored in a file....

* "use Math::MatrixSparse;" Load the module and make its methods and operators available. CREATION AND INPUT-OUTPUT METHODS * "Math::MatrixSparse->new($name)" "new Math::MatrixSparse($name)" Creates a new empty matrix named $name, which may be undef....

The design goals of this package are listed in the following table. * Pure Perl code, that means no external dependencies except core modules and other pure Perl modules. * Native data types for operands, that means no dedicated classes for vectors a...

NOTE: This module requires GSL 2.0 or higher. For more informations on the functions, we refer you to the GSL offcial documentation: <http://www.gnu.org/software/gsl/manual/html_node/>...
