LaTeXtaglet allows inclusion of mathematical equations in Javadocs. This project was originally developed by Stephan Dlugosz and hosted at SourceForge. The original source code is dependent of ... [More] Windows conventions for directories and files names. The modified version of LaTeXtaglet described here runs fine on unix platforms but was never tested on Windows. It's uncertain whether changes in the modified version were propagated back to the original code base as the original author apparently stopped improvements to the original code base. Hence, another code base was created under JQuantLib umbrella. JQuantLib uses LaTeXtaglet to generate nice Javadocs which contains UML diagrams and mathematical equations.

sMArTH is an online equation editor for MathML and LaTeX that is built on open Web standards. The editor itself uses a SVG interface and the application logic is implemented in ECMAScript using the ... [More] DOM. Both MathML and LaTeX are supported as exporting formats in addition to the SVG format. [Less]

jsTeXrender - an Online JavaScript LaTeX-equation render for WebsThis is a new innovation for displaying Mathematical formula on www. The aim is to help blogger and webmaster publish equations in ... [More] their website or blog with the LaTeX by installing a small javascript. You just simply write the equations using (or ), a HTML tag, in your web pages. Then, the online LaTeX render engine will convert the TeX/LaTeX code on your web page to equation image (png or gif) which can be displayed in any web browser, i.e., Firefox, MS Internet Explorer.

The project is wrapper for the NIST Refrence Properties Database for pure fluids and mixtures thermodynamic properties currently on Pure Fluid are supported The database website ... [More] [url:http://www.nist.gov/srd/nist23.htm] The aim of the project is to make the fluid or mixture as an object to be processed alone without the necessity to work with only one fluid/mixture per program sample code PureFluid Water = new PureFluid("Water"); PureFluid Ammonia = new PureFluid("Ammonia"); Ammonia.CurrentUnitsBasis = UnitsBasis.Mass_Basis; Water.CurrentUnitsBasis = UnitsBasis.Mass_Basis; for (int P = 100; P <= 600; P += 50) { Console.WriteLine("{0} {1} {2}", P, Water.GetSaturatedTemperature(P) - 273.15, Ammonia.GetSaturatedTemperature(P) - 273.15 ); } the managed library is making the transition between fluids internally and keeps you focused on what you are doing. I am planning to add MixedFluid class also to make some methods as ThermoDynamic Processes like fluid.AdiabaticCompress(); fluid.IsentropicCompress(); etc. Hope it will be useful for you as it was useful for me :) [Less]

Equation SolverWelcome to the Equation Solver. Equation Solver is an equation parser and solver for JScience and is the solution engine used for the Equation Solver web site. The Equation Solver ... [More] uses OOD Principals. Here's a sample unit test: String line = "(x-3)(x+5)-(x+2)(x-4) = 2x-5(x+4)"; EquationBuilder b = new EquationBuilder(); new EquationParser(b).parse(line); Equation e = b.build(); e.evaluate(); assertTrue(e.getAnswers().contains(Rational.valueOf("-13/7")));Currently in the process of developing a matrix parser and tools for differentiation (this is done in 0.0.2 and just needs testing), integration, and handling nested equations. I'm no math expert, so please check the issues list and let me know if you'd like to contribute. NOTE: To build and/or run the Equation Solver code you need to download JScience version 4.3 and add it to your classpath. Details located on the Developer's Guide ANOTHER NOTE: If you're looking for a web site that solves algebraic equations, try Equation Solver. [Less]

Yet another equation editor for Mac Os X

Project DescriptionA stand-alone program that can take MathML (acquired, e.g., from Microsoft Word 2007) and convert it to a meaningful set of C# statements, thereby facilitating domain-driven design ... [More] in engineering and mathematical applications. To see the program in action, watch the screencast. System RequirementsRequires .NET Framework 3.5 to run and Visual Studio 2008 + NUnit to compile. To use the functionality, a MathML-compatible editor is required. If using MS Word, make sure your Clipboard settings for equations are set to copy MathML. FeaturesCurrent version implements the following features: Variable naming (e.g., if we write x = y, both variables are defined as double x, y;). Multiplication sign addition (e.g., writing x = 2y results in the statement x = 2 * y;). Superscript and subscript. Superscript is taken to mean 'power of' and is realized with Math.Pow(). Subscript properly affects variable naming. Round and square braces are handled. Some replacements, e.g. replaces × with *. Substitutions, e.g., replacing 'e' with Math.E, are supported. Power inlining. Allows us to generate x*x instead Math.Pow(x, 2), which is much slower. An ExampleGiven this: The tool outputs this: p = rho*R*T + (B_0*R*T-A_0-((C_0) / (T*T))+((E_0) / (Math.Pow(T, 4))))*rho*rho + (b*R*T-a-((d) / (T)))*Math.Pow(rho, 3) + alpha*(a+((d) / (t)))*Math.Pow(rho, 6) + ((c*Math.Pow(rho, 3)) / (T*T))*(1+gamma*rho*rho)*Math.Exp(-gamma*rho*rho); [Less]

Mallory - Mathematics ActionScript Library - Advanced Math for ActionScript 3.0This is a library for doing advanced college level math (i.e. beyond calculus) with in ActionScript 3.0. PartsThis ... [More] library includes classes for working with Complex numbers Permutations Cycles Sets Algebraic structures(i.e. groups, rings, fields, etc.) Matrices (over algebraic structures) Numeric sequences Expression evaluation Vectors Polygons Statistical Analysis Graphing Current StatusThere are some sample programs made with Mallory here. On January 8th, I released an major update. Unfortunately, I haven't tested it very much so I know that it's full of bugs. I've improved the organization of the code somewhat, but it still needs a lot of work. I know specifically that the ComplexMath class has many comments that are completely wrong. I copied and modified the code from the RealMath, and forgot to change all of the comments. This latest update includes "Quickulator", a sample application that uses the Mallory code base. If anyone wants to help I, I could really use people to help me to test, debug, and comment the code. Any other ideas are also welcome. HistoryMain Actionscript ProjectI've been working on this project on and off since 2004. Since then, it's gone through numerous rewrites including transitions from actionscript to actionscript 2 and actionscript 2 to actionscript 3. Most of the ground work is done. There are some noticeable problems with the matrix (with decomposition) class and the expression evaluation class, but hopefully I'll solve those soon. Secondary Javascript ProjectThere is a very incomplete javascript implementation (MalloryJS) that I threw together one weekend, but I'm not sure how much effort I want to put into it as ActionScript has a lot of features not found in JavaScript. Perhaps I'll put this on hold until JavaScript 2 becomes a widely accepted standard. Future PlansIn the near future, I plan to implement the following features Example usage Improved commenting Unit tests Equation solving Polynomial manipulation Numeric/symbolic integration and differentiation Conic Sections [Less]
