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.

About this Package

An efficient, high level interface for the HDF5 data storage format. This package is part of ILNumerics Ultimate VS. It requires the Computing Engine package.

General Preparation

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

Quick Start (Computing Engine)

• reference the Computing Engine package in your project.

• reference the ILNumerics.IO.HDF5 package in your project.

• include the following 'using' directives (C#):

    using ILNumerics; 
    using ILNumerics.IO.HDF5; 
    using static ILNumerics.ILMath; 
    using static ILNumerics.Globals; 
  

• add this code in order to write a simple hdf5 file and to read it back in:

    using (var file = new H5File("myFile.h5")) {
        file.Add(new H5Dataset("myDataset", rand(1000, 1000))); 
    }
    using (var file = new H5File("myFile.h5")) {
        Array<double> A = file.First<H5Dataset>("myDataset").Get<double>();
        Console.Write($"First 10x10 elements: {A[r(0, 9), r(0, 9)]}"); 
    }
