Operation with currency values don't work fine with float or double types. This C++ library implements operators in a decimal fixed point (x100) package. This package use only integer type internally multiplied by 100.

Curv is a programming language for creating art using mathematics. It's a 2D and 3D geometric modelling tool that supports full colour, animation and 3D printing. Curv is a simple, powerful, dynamically typed, pure functional programming language. Curv is easy to use for beginners. It has a standard library of predefined geometric shapes, plus operators for transforming and combining shapes. These can be plugged together like Lego to make 2D and 3D models. Coloured shapes are represented using Function Representation (F-Rep). They can be infinitely detailed, infinitely large, and any shape or colour pattern that can be described using mathematics can be represented exactly. Curv exposes the full power of F-Rep programming to experts. The standard geometry library is written entirely in Curv. Many of the demos seen on shadertoy.com can be reproduced in Curv, using shorter, simpler programs. Experts can package techniques used on shadertoy as high-level operations for use by beginners.

These curvature filters were developed by Yuanhao Gong during his PhD studies. 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. Therefore, Curvature filters focus on minimizing the regularization term, whose minimizers are already known. For example, if the regularization is Gaussian curvature, the developable surfaces minimize this energy.

Implementation of various mathematical curves that define themselves over a set of control points. The API is written in Java. The curves supported are: Bezier, B-Spline, Cardinal Spline, Catmull-Rom Spline, Lagrange, Natural Cubic Spline, and NURBS.

Curve Generation eXtreme aims to implement various types of mathematical curves such as Hilbert and Sierpinski curves, as well as random generated plants, using L Systems and OpenGL / Mesa3D for displaying.

CurveDraw is a software that aim to draw 2D curves (Cartesian,polaire). The software is 100% Java.CurveDraw is based on JEP library (Java Math Expression Parser) .

This project has the role of simulating simple Curvilinear and Rectilinear Motions with an easy to use user interface. This program can be used for educational purposes as well as for any other purpose anyone would like. The executable file is a .jar files which means that it can run in any operating system that supports java. Above you can see a screenshot of the program while it is operating.

CutePy is a lightweight Qt-based Python 3 console with variable explorer, command history, syntax highlighting and customizable startup script. Originally it was developed for simple scientific calculations as a replacement for e.g. Windows calculator or Python IDLE. Therefore its main aim is to start fast and provide more comfortable dealing with variables based on the Python language. However in the end it is a regular Python console and therefore can be used for almost any task.

This project (CvHMM) is an implementation of discrete Hidden Markov Models (HMM) based on OpenCV. It is simple to understand and simple to use. The Zip file contains one header for the implementation and one main.cpp file for a demonstration of how it works. Hope it becomes useful for your projects.

To develop a software package for time series manipulation and cycles analysis. Cycles means repeated occurrences at nearly equal time intervals in any time series data. See http://www.cyclesresearchinstitute.org/ for a site about cycles.

D-Cog (Declarative-Cognition) is a Java based framework for training software components (reusable, object-oriented, interface-driven components). Instead of programmed, software components are trained by example to get the expected results.

C++ implementation of the DAWG and trimmed DAWG data structures. Supports basic string searching.

A freeware Qt based project which targets a Calculator which has views of bin/dec/hex in the same window. I have missed this feature in legacy calculators and some of the colleagues asked about it too, hence the origin of the idea.

DD-AVX: Library of high-precision operations accelerated by AVX. author's page http://www.slis.tsukuba.ac.jp/~s1530534/index.html e-mail hishinuma@slis.tsukuba.ac.jp Double-Double (DD) precision operations are used to reduce rounding errors and improve the convergence of Krylov subspace methods. This library has Double-Double precision operations accelerated by AVX and AVX2. AVX and AVX2 are intel SIMD instructions. They operate four double precision operation simultaneously. This library needs to merge "Lis" for DD precision iterative solvers. Official support "Lis" version is "lis-1.4.58." After merge "lis" and "DD-AVX," the interface is same as "lis." Lis web page http://www.ssisc.org/lis/index.en.html This library is managed by git. old version can search "code" page.
