c#矩阵代码

转置让我写成了对角线交换。。。

还是要记录下

对角线交换代码：

public int[][] Transpose(int[][] matrix) {
      int temp=0;      
    int m = matrix.Length, n = matrix[0].Length;      
       for(int i=0;i<m;i++)
       {
        for(int j=i+1;j<n;j++)
        {          
            temp=matrix[i][j];
            matrix[i][j]=matrix[j][i];
            matrix[j][i]=temp;           
        }
       }
       return matrix; 
    }

　转置代码：

public int[][] Transpose(int[][] matrix) {
        int m = matrix.Length, n = matrix[0].Length;
        int[][] transposed = new int[n][];//二维矩阵初始化
        for (int i = 0; i < n; i++) {
            transposed[i] = new int[m];
        }
        for (int i = 0; i < m; i++) {
            for (int j = 0; j < n; j++) {
                transposed[j][i] = matrix[i][j];
            }
        }
        return transposed;
    }
