This module provides function project() for computing intersection with upright line through input point [xi,yi]. You must specify points [x1,y1] and [x2,y2] of straight line. You can use list of imported functions or access functions via "Math::Proj...

Methods new "new" may be used as a class or object method. In the current implementation both have the same effect. "new" returns a new Math::Project3D object. You need to pass a number of arguments as a list of key/value pairs: plane_basis_vector =>...

This module may be used to plot the results of a projection from a three dimensional vectorial function onto a plane into an image. What a horrible sentence. Methods new new is the constructor for Math::Project3D::Plot objects. Using the specified ar...

This package contains the code for generating anonymous subroutines for use as functions with the Math::Project3D module. The package has no public subroutines and you should use it indirectly through the "new_function" method of Math::Project3D. Oh,...

An unscaled DCT-II implementation for 1D and NxN 2D matrices implemented in XS. For array sizes which are a power of 2, a fast algorithm (FCT) described by Lee is used (with the addition of a coefficient table that makes it even faster than some comm...

Man, if that synopsis don't say it all, what can I possibly add? :-) OK, as mentioned above, this is a fun project. The plan, not necessarily all implemented at the first release, is to provide many kinds of operations on the polynomials that intimid...

This module adds support for 64 bit integers, signed and unsigned, to Perl. Exportable functions int64() int64($value) Creates a new int64 value and initializes it to $value, where $value can be a Perl number or a string containing a number. For inst...

This module provides an interface for performing single modulo arithmetic operations on Galois Field polynomials in GF(2^8), GF(2^16) and GF(2^32). All values to be operated on are simple Perl numeric scalars which are taken to represent polynomials ...

"Clipper" is a C++ (and Delphi) library that implements polygon clipping. Exports The module optionally exports a few constants to your namespace. Standard Exporter semantics apply (including the ":all" tag). The list of exportable constants is compr...

What! Yet another module to manipulate polynomials!! No, don't worry, there is a good reason for this one ;) I needed (for my work at a large financial institution) a robust way to compute the internal rate of return (IRR) of various cashflows. An IR...

This package implements classic geometry methods. It should be considered alpha software and any feedback at all is greatly appreciated. The following methods are available: vector_product. Also known as the cross product, given two vectors in Geomet...

This function uses George Marsaglia's Multiply With Carry algorithm to produce uniformly distributed unsigned integers. * $random = sRNG('seed1','seed2') input: seed1 [optional] seed2 [optional] return: an unsigned random integer 1 -> 2^32 -1 Startin...

This package contains solves mathematical problems relating to loans and annuities. The attributes that are used in the equations may be set on a per-object basis, allowing you to run a set of different calculations using the same numbers, or they ma...

This module handles padding numbers to achieve a certain presentation. This module currently provides just a single function but may provide decimal point padding and other functions in the future....

A module for number theory in Perl. This includes prime sieving, primality tests, primality proofs, integer factoring, counts / bounds / approximations for primes, nth primes, and twin primes, random prime generation, and much more. This module is th...

The internal rate of return (IRR) is a powerfull tool when evaluating the behaviour of a cashflow. It is typically used to assess whether an investment will yield profit. But since you are reading those lines, I assume you already know what an IRR is...

This is a simple Min/Max collector. Meaning - while you are in some kind of process, and would like to get some infomation on sets of numbers you are working with, create an instance of this object, throw numbers it's way and at the end of your proce...

This is an object to describe a list of mathematical ranges (min-max type) which are disjoint....

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 contains 2d vector-based objects intended as base classes for 2d games programming. Most of the objects have collision detection (among other methods). All objects are immutable in so far as their methods return new objects everytime. The...
