Compatibility

ILNumerics is compatible with all .NET runtimes since .NET Framework 4.6.1., including .NET Core, .NET 5.0, .NET 6.0.

We've invested great effort to 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. 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. It allows to connect your data to any 3rd party without hassle. Further, it is able to host your data on any computational resource found, including CPUs and GPUs - key for heterogeneous, parallel computing.

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 Windows.Forms and ILNumerics.Drawing.Platforms.

General Preparation

• install the ILNumerics Visual Studio extension
• download your trial license.
• activate your seat.

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.Bitmap.Save("image.png");
    }
  

• Hit F5 and find the result in your /bin/Debug/ folder: image.png

• Read the beginners guide and start implementing your own scenes!
