The "Math::VectorReal" package defines a 3D mathematical "vector", in a way that is compatible with the previous CPAN module "Math::MatrixReal". However it provides a more vector oriented set of mathematical functions and overload operators, to the "...

A simple pure perl module to manipulate vectors of any dimension. The function "V", always exported by the module, allows one to create new vectors: my $v = V(0, 1, 3, -1); Vectors are represented as blessed array references. It is allowed to manipul...

This module reimplements most of the functions in Math::Vector::Real in XS for a great performance boost. Once this module is installed, Math::Vector::Real will load and use it automatically....

This module extends the Math::Vector::Real package adding some methods for random generation of vectors. Methods The extra methods are: Math::Vector::Real->random_in_box($dim, $size) $v->random_in_box When called as a class method, returns a random v...

This module implements several algorithms related to polygonal chains or polylines. Note that the module can handle polylines in spaces of any dimension (not just 2D). API $p = Math::Vector::Polyline->new(@vectors) Creates a new polyline object. $d2 ...

This module implements several algorithms for finding the maximum distance between any two vectors from a given set (AKA the set diameter) and some two vectors that are that far away. METHODS The methods available are as follows: ($d2, $v0, $v1) = Ma...

This module is able to find for every point in a given set its nearest neighbour from the same set. Note: currently the "neighbors" method is just a thin wrapper for the neighbor look-up algorithm provided in Math::Vector::Real::kdTree which is a cou...

This module implements a kd-Tree data structure in Perl and common algorithms on top of it. Methods The following methods are provided: $t = Math::Vector::Real::kdTree->new(@points) Creates a new kd-Tree containing the given points. $t2 = $t->clone C...

This module allows to calculate the density of a mixture of n multivariate normal simetric distributions. Given a multivariate normal simetric distributions in IR**k (IR := the real numbers domain) such that its density function can be calculated as....

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....

Introduction Assume that you have a list of vectors v_1, v_2, v_3, ..., v_n and an equally sized list of vectors w_1, w_2, ..., w_n. A way to quantify how similar these lists are to each other is to compute the sum of the squared distances between th...

This is alpha software. The API is stabilizing and the test suite at least deserves that name by now, but input checks and documentation are still sparse. However, release early, release often, so here we go. Aims This distribution serves two purpose...

The typical user will not interact directly with this class. It unifies the access to different sources of a vector. This can be * a reference to an array of numbers In this case, the value method will return a Math::Vector::Real object consisting of...
