ILNumerics Ultimate VS

This package is part of ILNumerics Ultimate VS - a comprehensive, powerful platform for high-performance technical application development on .NET.

ILNumerics.Computing

ILNumerics centers around ILNumerics.ONAL - the free and open-source core language of the ILNumerics ecosystem. It provides all fundamental numerical language features in a common, stable, deployable and maintainable implementation.

ILNumerics.Computing extends the open-source ILNumerics.ONAL language core into a commercial-grade foundation for professional .NET applications, visualization extensions, domain-specific toolboxes, deployment, and no-effort auto-optimization.

Start with ILNumerics.ONAL to write and validate your algorithms in the free and open-source core language; the same algorithms can then be executed, extended, and further developed with ILNumerics.Computing without changing the mathematical source code.

Core Features of ILNumerics:

• Fast numerical algorithms in Matlab(R) and numpy style
  • Efficient n-d array classes: ILNumerics.Computing (online docu)
  • Large selection of fundamental, mathematical array functions
  • Stable, high-level linear algebra and FFT interface, cross-compiled from netlib's sources to managed ILNumerics. Native (MKL) versions can optionally be used.
• ILNumerics Accelerator JIT compiler: autonomous, decentralized auto-parallelization and low-level kernel generation for execution speed beyond traditional optimization techniques (2026' paper, benchmarks here, here and here)
• Stable, mature API (no breaking change since 2018).
• Toolboxes for
  • Interpolation: ILNumerics.Toolboxes.Interpolation (online docu)
  • Optimization: ILNumerics.Toolboxes.Optimization (online docu)
  • Statistics: ILNumerics.Toolboxes.Statistics (online docu)
  • HDF5: ILNumerics.IO.HDF5 (online docu)
• Flexible, good looking, fast and robust 2D and 3D visualizations.
  • ILNumerics Visualization Engine: ILNumerics.Drawing: (online docu)
    • Scene graph based rendering of line-, scatter-, XY-, contour-, surface plots.
    • Compose complex scenes built of simple point-, lines-, and triangle-shapes.
    • Output to common image formats and SVG.
  • WindowsForms and WPF Controls: ILNumerics.Drawing.Platforms
    • Interactivity: ILNumerics.Drawing.Controls.[WinForms|WPF].Panel
    • Hardware acceleration (OpenGL)
    • Fully featured software renderer fallback.
  • ILNumerics Drawing Extensions: ILNumerics.Toolboxes.Drawing2
    • Bar-, spline-, region-, error-, candlestick-, fill area-, stacked area-, box plots.
    • More and faster surfaces, smooth surface.
• Visual Studio Tools: get the free Array Visualizer from MS Marketplace

Compatibility

ILNumerics is compatible with all .NET runtimes since .NET Framework 4.6.1., including .NET Core, .NET 8.0. and newer.

We've invested great effort to auto-translate and keep up to date the quasi standard algorithms for all computational routines, including linear algebra, FFT and optimization methods. These purely managed implementations are the first to bring professional robustness and precision to .NET. Hence, ILNumerics runs efficiently on any platform supported by .NET! Optionally, native libraries can be used to replace the managed default implementation. For the Windows platform, such native, optimized libraries are provided, too.

Performance

ILNumerics apps are typically much faster than alternatives: faster to implement and faster during execution. We've invented groundbreaking new auto-parallelization techniques which make full use of modern, parallel hardware with unseen automatic efficiency. Further, with ILNumerics the size of your data is not limited by the managed heap. ILNumerics n-dimensional Array<T> bridges the gap from high-level mathematical expressions down to native memory robustly, efficiently, and transparently. Moreover, it allows to connect your data to any 3rd party interface without hassle.

ILNumerics.Toolboxes.Drawing2

This package implements extensions to the Visualization Engine. It adds more plot types, faster surfaces and more high-level features (as smooth surfaces) to your visualizations. The types in this modules can be used for general visualizations and plots as well as for interactive apps, based on WPF or WindowsForms (see: ILNumerics.Drawing.Platforms).

Quick Start (Visualization Engine)

• reference the Drawing2 package in your project.

• start with a new console application (C#)

• include the following code into your Program.Main() method (C#). It creates random data, a new scene, use the data to add a new FillArea plot and renders the plot to a bitmap image (offscreen rendering).

   static void Main(string[] args) {
   // create a new scene, with a bar plot of random data 
   var scene = new Scene();
   // create some data
   Array<double> A = arange<double>(1, 10).T.Concat(rand(1, 10), 0);
   // create a fill area plot
   var plot = new FillArea(A, fillColor: System.Drawing.Color.LightGray); 
   // add the plot to the scene 
   scene.Add(new PlotCube(twoDMode: false) { plot });
  
   // add-on: access the line inside the plot and configure its width.
   // Lines in ILNumerics.Drawing are mostly Lines objects - capable for rendering many lines efficiently.
   var lineplot = plot.First<Lines>();
   lineplot.Width = 3;
   lineplot.DashStyle = DashStyle.Dotted; 
  
   // signal that your scene is ready for rendering
   scene.Configure();
  
   // (offscreen) render the scene to a bitmap, using GDIDriver
   var gdi = new GDIDriver(1000, 1000, scene);
   gdi.Render();
   gdi.BackBuffer.SaveBitmap("image.png");
   }
