C#矩阵相乘

第一种：交叉数组形式

1. /// <summary>

2. /// 矩阵乘法

3. /// <param name="matrix1">矩阵1</param>

4. /// <param name="matrix2">矩阵2</param>

5. /// <returns>积</returns>

6. private static double[][] MatrixMult(double[][] matrix1, double[][] matrix2)

7. {

8. //matrix1是m*n矩阵，matrix2是n*p矩阵，则result是m*p矩阵

9. int m = matrix1.Length, n = matrix2.Length, p = matrix2[0].Length;

10. double[][] result = new double[m][];

11. for (int i = 0; i < result.Length; i++)

12. {

13. result[i] = new double[p];

14. }
