怎么用C#进行矩阵运算,要转换为多维数组还是怎么办？

[chunjinyumen]

比如有格网点x=[1 1 1 1 1
2 2 2 2 2
3 3 3 3 3
4 4 4 4 4
5 5 5 5 5]
格网点y=[1 1 1 1 1
2 2 2 2 2
3 3 3 3 3
4 4 4 4 4
5 5 5 5 5]
现在我有个点(x=1.2,y=2.3),想求出该点在那个小格网中？

试试

            int[] arr = { 1, 2, 3, 4, 5, 
                          6, 7, 8, 9, 10, 
                          11, 12, 13, 14, 15 };
            double x = 2.3;
            int Split = 5;
            int resultX = (int)x;
            int resultY = (int)(x * 10 % 10);
            int result = resultX * Split + resultY - 1;
            Console.WriteLine(arr[result]);
