Linear Algebra Library

Question

Where can I find similar function as numpy.linalg.norm (Python) for C++ or C#? This function is able to return one of seven different matrix norms, or one of an infinite number of vector norms, depending on the value of the ord parameter.

Answer 1

根据您的平台和口袋的深度，您可能对英特尔的 MKL感兴趣，它可以从 C++ 和 C# 调用

Answer 2

See if this library makes sense for you:

Boost

Answer 3

您可以使用 Fortran 编译器编译blas和lapack ，并在您的 C++ 程序中链接它们。

Answer 4

也许alglib适合你？

Answer 5

For C# the numerics part of the Math.NET project may be what you want.

Answer 6

You can use Vector2.Length() Example:

using System.Numerics;

namespace LinearAlgebraCSharp
{
    class Program
    {
        static void Main(string[] args)
        {

            Vector2 vec1 = new Vector2(2, 3);

            // Equivalent of <numpy.linalg.norm>
            float vectorModule = vec1.Length();
        }
    }
}
