Plot data in SVG format using C++ library
The SVG_plot C++ library allows, with a few lines of C++ code, to add plotting of data, held in STL containers like vector and map, output as SVG files that can be viewed by all modern browsers. 1D, 2D and Boxplots can be produced, and there are a myriad of options to control appearance. The plots are very high quality and can be expanded without loss of quality (no pixelation!) but are tiny, (compared for a Microsoft Excel plot, for example) and are easily compressible, making them suitable for real-time transmission and update. The SVG_plot project was originally written by Jake Voytko in 2007 as a Boost-sponsored Google Summer of Code project in 2007. It has been maintained and enhanced since then in Boost Sandbox, but is judged unsuitable for a Boost Library, so now being made more widely available here. Version 2 adds representation of uncertainty estimates as numbers and zones.
Runge is an Interactive Solver for Systems of Differential Equations
Runge is an Interactive Solver for Systems of Ordinary Differential Equations. It solves initial value problem (aka Cauchy problem). Few advantages Runge provides: It's fast. It utilizes BLAS and LAPACK libraries optimized for modern multi-core processors. It's interactive. It allows you to start a solution by mouse click on a plane. It's precise. It uses Runge Rule to adjust step length to satisfy required precision on each step. It's effective. When it needs to compute derivatives (Jacobian matrix, for example) it does that analytically, i.e. without using numerical methods. It's portable. It works on Windows and Linux 32 and 64 bit and Mac OS X 64 bit. It's open. It allows you to implement and embed your own algorithms (aka "solvers"). It's easy to use. It allows to export results to MS Excel and MATLAB. It's multilingual. It currently supports Englis and Russian languages. It's free. It's distributed under the Boost Software License.
