Maxima -- GPL CAS based on DOE-MACSYMA
Computer Algebra System written in Common Lisp
Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0, giving the symbolic results [x=r+s, x=-s]. It can also calculate with exact integers and fractions, native floating-point, and high-precision big floats. Maxima has user-friendly front-ends, an online manual, plotting commands, and numerical libraries. It features its own programming language, and many users have contributed useful packages in various areas over the decades. ... -

Makes magic squares.
...There are 3 similar programs: CompleteSquare, CompleteSquareSteps, and MagicSquares. Given an input square with some cell values between 1 and NxN specified, (and other cell values 0), CompleteSquare attempts to complete a magic square by placing the remaining values. The square type can be input as semimagic, magic, or associative. For successful solutions, CompleteSquareSteps shows the steps of the search. The number exchanges at each step and the intermediate squares are written to files. MagicSquares does not require an input file. ... -

MandelbrotExplorer
A program to calculate and represent the Mandelbrot set
...The user disposes of a graphical interface to control the program and modify conveniently some parameters, like the XY-scales, the XY map area, the Julia seed for the complex series iteration of Z(n+1)=Z(n)^2+a, being Z(0)=(X0,Y0) the seed, and "a in XY" the points to be calculated. The user can enter (among other parameters) the desired convergence-radius R for the series, and/or the number of maximal iterations N for the generator-equation in Z. -

PhaseSpace
Analyse dynamical systems, plot its phase space and critical points.
Phase Space is born out of the need of a simple yet powerful open source tool to study dynamical systems. PhaseSpace allows you to plot the phase space of the dynamical system you are studying, its critical points and the curves of slope zero and infinite.It can also plot the solutions of the system and it's vector field. To use PhaseSpace you'll need to have Python installed along with Matplotlib and Numpy. -

API for all possible cellular automata that work same at all angles
...You can create any function, or to get started try the visual function editor where each click changes if a column is sine/sigmoid/half/double/exp/etc or which of the 0, 1, or 2 columns to the left are its params. Every click changes the patterns of waves seen on the left, which run that function you visually built at each point. -

Bit level lambda continuations and nothing else - Queue automata
...To deal with the Halting Problem, computing and data are navigated using debugger ops: linearForward and treeForward, which navigate an astronomically large bit string where 1 is ( and 0 is ). All pairs are derived from (). For example, true is represented as ((()())()), and false is (()(()())). It appears related to the church encoding of lambda where T chooses first parameter and F chooses second, of a pair. Continuations are nearly finished code and are represented as a pair of stack and queue. The stack is a linked list of pair of true or false and object pushed on the stack. ... -

CalcMatr
Calculations with matrixes of integers or fractions up to 4 x 5
...Matrices (or their elements) and systems of linear equations can be also generated by the app, to practice with operations and propieties. The app calculates the matrix range, determiner of square matrices, traspose, inverse of inversible matrices (that is, square matrices with non zero determiner), the matrix of adjuncts, the forms of Gauss and Gauss-Jordan. It allows submatrices extraction by selection of rows and columns. Combined operations among matrixes: addition, subtraction, product, raising to a power Systems of equations up to 4 equations with 4 unknowns, also introduced by the user or generated by the app: it makes the classification of the system and the resolution in consistent systems. -

Fingerprint Recognition System
Fingerprint Recognition System 5.3 - Matlab source code
The proposed filter-based algorithm uses a bank of Gabor filters to capture both local and global details in a fingerprint as a compact fixed length FingerCode. The fingerprint matching is based on the Euclidean distance between the two corresponding FingerCodes and hence is extremely fast. We are able to achieve a verification accuracy which is only marginally inferior to the best results of minutiae-based algorithms published in the open literature. Our system performs better than a... -

Immutable Sparse Wave Trees (WaveTree)
Realtime bigdata tool for bit strings up to 2^63 based on AVL forest
...Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. Main functions on bits are substring, concat, number of 0 or 1 bits, and number of bits (size). All those operations can be done millions of times per second regardless of size because the AVL forest reuses existing branches recursively. Theres a scalar (originally for copy/pasting subranges of sounds) and a bit Java package. Sparse n dimensional matrix. -

fastest primes
A fast prime number generator based on the Sieve of Eratosthenes
The purpose of this project is to make a prime number generator that offers many user adjustable settings and that is also very fast. While there are other prime number generators that can still beat this one in speed, no other ones that I am aware of allow the level of adjustment of sieve size that this one does. If you are running 64-bit Windows, make sure to download the 64-bit executable as it is faster than the 32-bit executable. -
