以下是使用C#实现SVD奇异值分解的示例代码:
```csharp
using System;
using MathNet.Numerics.LinearAlgebra;
class Program
{
static void Main()
{
// 创建一个矩阵
Matrix<double> matrix = Matrix<double>.Build.DenseOfArray(new double[,]
{
{1, 2, 3},
{4, 5, 6},
{7, 8, 9}
});
// 进行SVD分解
Svd<double> svd = matrix.Svd();
// 获取奇异值矩阵
Matrix<double> singularValues = svd.W;
// 打印奇异值矩阵
Console.WriteLine("奇异值矩阵:");
Console.WriteLine(singularValues);
// 获取左奇异向量矩阵
Matrix<double> leftSingularVectors = svd.U;
// 打印左奇异向量矩阵
Console.WriteLine("左奇异向量矩阵:");
Console.WriteLine(leftSingularVectors);
// 获取右奇异向量矩阵
Matrix<double> rightSingularVectors = svd.VT.Transpose();
// 打印右奇异向量矩阵
Console.WriteLine("右奇异向量矩阵:");
Console.WriteLine(rightSingularVectors);
}
}
```
