Swift Numerics
Advanced mathematical types and functions for Swift
Swift Numerics is a foundational library that extends the Swift standard library with essential numerical protocols, types, and functions needed for scientific and systems programming. It defines generic abstractions over real and complex numbers so algorithms can be written once and work across concrete floating-point types. The package includes RealModule utilities and a full Complex type with the expected arithmetic and transcendental functions, bridging a long-standing gap for numerics in Swift. API design follows Swift’s emphasis on value semantics and protocol-oriented programming, enabling compiler optimizations and predictable performance. ... -

Napkin
An Infinitely Large Napkin
...It is not a polished textbook full of full proofs; rather it offers clean definitions, theorem statements, intuitive motivations, and informal sketches of why things work, with the goal of building conceptual understanding. The coverage spans undergraduate and early graduate topics, designed to show how different areas of math fit together—linear algebra, analysis, topology, number theory, and more—without going deeply into every subtopic. Because it is written in LaTeX (with supporting Asymptote or other tools), readers can compile their own version, and the repository integrates diagrams, flowcharts, and supplementary files. -

Quaternion toolbox for Matlab
Quaternion and octonion toolbox for Matlab
Quaternion toolbox for Matlab is a toolbox that extends Matlab to handle matrices of quaternions with real and complex components. Many Matlab operators and functions are overloaded to work for real quaternion and complexified quaternion matrices. Version 2 of the toolbox adds support for octonions. Version 3 adds symbolic computation with quaternions, provided that you have the Symbolic Math Toolbox (if you don't the numeric functionality will still work). -

seaborn
Statistical data visualization in Python
...Its dataset-oriented, declarative API lets you focus on what the different elements of your plots mean, rather than on the details of how to draw them. Behind the scenes, seaborn uses matplotlib to draw its plots. For interactive work, it’s recommended to use a Jupyter/IPython interface in matplotlib mode, or else you’ll have to call matplotlib.pyplot.show() when you want to see the plot. -

Clifford Multivector Toolbox
A toolbox for computing with Clifford algebras in MATLAB
This is a toolbox (software library) for computing with matrices of Clifford algebra multivectors in MATLAB. It is designed to handle numerical computations with matrices as far as these are defined for matrices of multivectors. The toolbox is designed to work in the same way as MATLAB's own functions by overloading standard MATLAB functions with Clifford multivector versions. The toolbox can compute with any Clifford algebra with signature (p,q,r) but only with one algebra at a time. From version 2 of the toolbox onwards, computation is also supported with conformal geometric algebras (CGA), based on an underlying Clifford algebra to provide the numerical computation. ... -

polynomial-roots-calculation
Application for calculating the real roots of a polynomial
...It is not a very eficient way, as we must calculate al the derivatives of the polinomial, implying very high numbers (n!), that make the needed precision increase, making the computational complexity for high-degree polinomials poor. But I have been able to make it work with a 40-degree polynomial, with two very proximal zeroes arround x=1000. It needs a precision of arround 60 digits. The problem comes with very-high degree polynomials. The higher is the degree, the faster the execution time increases. But for common examples, the application does the job well.

slimcpplib
Simple Long Integer Math for C++
SLIMCPP is C++ header-only library that implements long integers that exceed maximum size of native type supported by a specific compiler by 2-4 times. All classes, methods and functions were not created or designed to work with huge numbers, for which there are specialized big integer mathematical libraries. In some cases, it is necessary to temporarily perform calculations with precision exceeding the maximum supported size of integers, and then return the result to its native size again. -

SODE
Program to solve differential equations using long Taylor series
Program to generate a program to numerically solve either a single ordinary differential equation or a system of them.It is a Ruby program, now called omnisode, which generates either Ruby, C, C++, Maple or Maxima code. Code can be generated for all languages under Linux. Ruby can be generated under Windows. All can be generated under cygwin, but would need work on execution of Maple. Omnisode itself is Ruby, which is needed in all cases to generate the program. -

hn++
Two Neighbours and Hermitian Neighbours in C++
Two-Neighbours (based on the work of B. Hemkemeier) and Hermitian Neighbours (based on the work of A. Schiemann) rewritten in modern C++. Based on a geometrical method used by Witt and Kneser, HN++ (contains TN and HN) classifies genera of lattices. Building upon those ideas and the older celebrated programs TN and HN, HN++ contains various methods to analyse invariants of the constructed lattices as well as more randomized algorithms to quickly search through large genera. -

HistoryCal
A calculator to work with historical dates and calendars.
HistoryCal is a practical calculator designed to work with historical dates and calendars. The calculator will allow you to work with many different world calendar schemes and calculate ranges and ages based on these calendars. The calculator also has a script language that allows you to create variations of the built-in calendars: calendars that shift the new year to a different day; hybrid calendars that switch between schemes; local observational calendars that depend on a particular location; year counts that change for specific eras (regnal calendars) and calendars that require adjustment due to subtle differences in calculation. -

CurvatureFilter
Curvature Filters are efficient solvers for Variational Models
...MC filter and TV filter are exactly the same as described in the paper. However, the GC filter is slightly modified. Please cite the following papers if you use a curvature filter in your work. Traditional solvers, such as gradient descent or Euler Lagrange Euqation, start at the total energy and use diffusion scheme to carry out the minimization. When the initial condition is the original image, the data fitting energy always increases while the regularization energy always reduces during the optimization. Thus, regularization energy must be the dominant part since the total energy has to decrease. ... -

Econball
Equation of stock trading simplified to game of moving resizing balls
The econ theory is the value of buy and sell are usually equal, at whatever free market price at the time, so if we trade between 2 things, holding the total of those 2 equal eachother, then you can buy without anyone selling, or sell without anyone buying. Just change from one equal valued type to the other, and the total of all the A's and all the B's are scaled instantly to be the same amounts. Those who change to the majority side lose, and those who change to the minority side win,... -

physicsmata
API for all possible cellular automata that work same at all angles
Its strange how the "sorted pointers" normalizing makes just about any random function, as long as it connects the inputs to the outputs on some path, vibrate as some nonlinear shape of wave. This could be used as a game interface for evolvable musical instruments or fluid puzzle games. Physicsmata is similar in effect to SmoothLife but simpler and pure Java. The cellular automata API takes a function to run at each point. Its parameters are sums of screen brightness (n color dimensions are...
