F2what is an open source project to translate algorithmic fortran to a variety of languages (java, dotnet and VBA so far). It offers a Fortran77 parser with code transformations, variable disambiguation, and modular output to other programming languages. It also offers already translated versions of Lapack and quadprog to Java, .Net and VBA, to give access to SVD, LU, QR, Cholesky, eigenvalue decomposition, linear system solving and QP optimization in those three languages.

Software for calculating geometric properties of cross sections and polygons. Calculates: area, moments of inertia, product of inertia, radius of gyration, section modulus, among others. It also supports import and export of CSV, JSON and DXF files. Able to do geometric transformations and 2D and 3D visualization of the cross sections.

Math.NET aims to provide a self contained clean framework for symbolic mathematical (Computer Algebra System) and numerical/scientific computations, including a parser and support for linear algebra, complex differential analysis, system solving and more

Linear Program Solver (Solvexo) is an optimization package intended for solving linear programming problems. The main features of the Solvexo are: · Solvexo solver is based on the efficient implementation of the simplex method (one or two phases); · Solvexo provides not only an answer, but a detailed solution process as a sequence of simplex matrices, so you can use it in studying (teaching) linear programming. · Solvexo provides a solution with the graphic method for problems with tow variables. · This updated version includes two languages English and French.

The project is in a very early state and the working parts aren't well tested! Currently it's possible to do basic calculations with multivectors. A lot of operators are overloaded so that you can write your calculations in C# source code almost like you would do in a math software. There is also an extension library providing a control which can visualize multivectors. Visualization is based on OpenGL through the OpenTK library. At the moment I'm working on improvements of the functionality of this library.

The aim of the project is to provide open source collection of algorithms in the field of spectroscopy: data handling and processing, modeling and artificial intelligence tools.
