在C#中更新矩阵类的实例值

public class Matrix
{
    public int Rows { get; set; }
    public int Columns { get; set; }
    public double[,] Data { get; set; }

    public Matrix(int rows, int columns)
    {
        Rows = rows;
        Columns = columns;
        Data = new double[rows, columns];
    }
}

Matrix matrix = new Matrix(3, 3);
matrix.Data = new double[,]
{
    { 1, 2, 3 },
    { 4, 5, 6 },
    { 7, 8, 9 }
};

matrix.Data[0, 0] = 10;

double updatedValue = matrix.Data[0, 0];
