vectorize an array in csharp

To vectorize an array in C#, you can use the System.Numerics namespace which provides support for SIMD (Single Instruction Multiple Data) instructions in C#. Here is an example code snippet that demonstrates how to vectorize an array using Vector<T>:


main.cs
using System;
using System.Numerics;

class Program {
    static void Main() {
        float[] array = new float[10000];

        Random r = new Random();
        for (int i = 0; i < array.Length; i++)
            array[i] = r.Next(0, 100);

        Vector<float> vectValue = new Vector<float>(2.0f);
        for (int i = 0; i <= array.Length - 8; i += 8) {
            Vector<float> vector = new Vector<float>(array, i);
            vector *= vectValue;
            vector.CopyTo(array, i);
        }

        Console.WriteLine("Array Values:");
        foreach (float value in array)
            Console.Write(value + " ");
    }
}

In this example, the Vector<float> class is used to read, modify and write the data in the array. The vector multiplication operation is performed on each block of 8 floats in the array, which provides a significant performance boost compared to scalar operations.
