矩阵转置

矩阵转置

C 实现

#include<stdio.h>
#define ROW 4
#define COL 4
int M[ROW][COL] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16};
main(){
    int i, j, t;
    printf("Before transposition:
");
    for (i = 0; i < 4; ++i){
        for (j = 0; j < 4; ++j){
            printf ("%d	", M[i][j]);
        }
        printf("
");
    }
    for (i = 0; i < 4; ++i){
        for(j = i;j < 4; ++j){
            t = M[i][j];
            M[i][j] = M[j][i];
            M[j][i] = t;
        } 
    }
    printf("After transposition:
");
    for (i = 0; i < 4; ++i){
        for (j = 0; j < 4; ++j){
            printf ("%d	", M[i][j]);
        }
        printf("
");
    }  
}
