Math Objects is a math template library written in C++ using generic programming techniques. In order to use the "Math Objects" library, the user only has to include the header files he needs (e.g. Matrix.h, Polynomial.h etc.).
In order to compile the library the user needs an ISO/IEC 14882:1998 standard compliant C++ compiler (e.g. one that supports partial template specializations).
The math library has math objects like matrices, polynomials, rational functions, extended precision numbers, complex numbers etc. that can be handled in a similar way like basic numerical types (e.g. integers or floating point numbers).
One can access properties of a mathematical type through a (partial) specialization of a traits class for that type (AlgebraicTraits). Having the traits classes to expose properties of mathematical objects, one can define for example matrices of polynomials having extended precision complex coefficients and apply to them basic linear algebra algorithms using normal C++ syntax.
This library also implements two functions using two deterministic algorithms that compute the Smith form for polynomial matrices, and the Smith-McMillan form of a transfer functions matrix also keeping track of the transformation matrices.
These algorithms can be used to describe a MIMO (multi input-multi output) system by means of its zeros and poles and also give the MFD (matrix fraction description) of the system.
Enhancements:
- Recoded the LongInt class aiming for better runtime efficiency.

MathWar project is a flashcard math game for kids.

MathWar is a flashcard math game in which the child plays against the computer to solve simple addition, subtraction, and multiplication problems before the computer player answers.

MathWar is aimed at kids who are just learning their math facts, and can easily be tailored to fit different skill levels.

Math::ODE Perl module allows you to solve N-th Order Ordinary Differential Equations with as little pain as possible.

Currently, only IVPs (initial value problems) are supported, but native support for BVPs (boundary value problems) may be added in the future. To solve N-th order equations, you must first turn it into a system of N first order equations, as in MATLAB.

TuxMathScrabble is a math-version of the popular board game for children aged 4-10. The game features drag-and-drop tiles for the user, while Tux moves his own.

The game challenges young people to construct compound equations and consider multiple abstract possibilities.

Dancing penguins come out of the tiles when your move is correct (like a cuckoo-clock). Tux is animated as well.

Ump is a program in which all sorts of calculations can be done, from the simplest to the more advanced. It handles complex numbers and matrices of those.

The complex numbers are built up by either floating point values or ratios of arbitrary sized integers. Ump also draws graphs, ordinary, polar, and parameter, which is done through an easy to use user interface.

Unnamed Math Program is also possible to write your own functions using the built in editor.

Math::Polynomial::Solve is a Perl module to find the roots of polynomial equations.

SYNOPSIS

use Math::Complex; # The roots may be complex numbers.
use Math::Polynomial::Solve qw(poly_roots);

my @x = poly_roots(@coefficients);
or
use Math::Complex; # The roots may be complex numbers.
use Math::Polynomial::Solve qw(poly_roots get_hessenberg set_hessenberg);

#
# Force the use of the matrix method.
#
set_hessenberg(1);
my @x = poly_roots(@coefficients);
or
use Math::Complex; # The roots may be complex numbers.
use Math::Polynomial::Solve
qw(linear_roots quadratic_roots cubic_roots quartic_roots);

# Find the roots of ax + b
my @x1 = linear_roots($a, $b);

# Find the roots of ax**2 + bx +c
my @x2 = quadratic_roots($a, $b, $c);

# Find the roots of ax**3 + bx**2 +cx + d
my @x3 = cubic_roots($a, $b, $c, $d);

# Find the roots of ax**4 + bx**3 +cx**2 + dx + e
my @x4 = quartic_roots($a, $b, $c, $d, $e);

Math::CDF is a Perl module to generate probabilities and quantiles from several statistical probability functions.

SYNOPSIS

use Math::CDF;

$prob = &Math::CDF::pnorm(1.96);

if( not defined($z = &Math::CDF::qnorm(0.975)) ) { die "qnorm() failed"; }

or

use Math::CDF qw(:all);

$prob = pnorm(1.96);

This module provides a perl interface to the DCDFLIB. See the section on DCDFLIB for more information.

Functions are available for 7 continuous distributions (Beta, Chi-square, F, Gamma, Normal, Poisson and T-distribution) and for two discrete distributions (Binomial and Negative Binomial). Optional non-centrality parameters are available for the Chi-square, F and T-distributions. Cumulative probabilities are available for all 9 distributions and quantile functions are available for the 7 continuous distributions.

All cumulative probability function names begin with the character "p". They give the probability of being less than or equal to the given value [ P(X<<less
