Getting Started with ILNumerics

This guide shows how to create your first ILNumerics project, run numerical array code, enable acceleration in Release mode, and generate a simple 3D plot from a .NET console application.

Prerequisites

Basic experience with the .NET command-line interface
.NET SDK 8.0 or later
A terminal or Visual Studio 2022

Open a terminal, create a new Console project and add the ILNumerics.Computing package:

Modify the auto-created Program.cs file to contain 'Console.WriteLine(ILNumerics.ILMath.rand(10, 10));' and run the app:

Now, let's accelerate! Open the auto-created Program.cs file and replace its content with the following code:

Run the application in Release mode to enable ILNumerics Accelerator. The example computes the same expression twice: once as a reference and once with accelerated execution. Both computations likely happen in parallel. The results are then compared to verify correctness.

Create a 3D plot

Add the ILNumerics.Drawing package to create a static, offscreen visualization from numerical data.

The example replaces the data with a function over a regular grid, renders the scene offscreen and saves the result as an image file, so it also works from a console application.

The generated file shows:
