C语言矩阵转置函数实现

int** transposeMatrix(int **a, int row,int col){
    int **b = (int **)malloc(sizeof(int *)*col);
    for(int i = 0; i < col; i++){
        b[i] = (int *)malloc(sizeof(int)*row);
    }
    for(int i = 0; i < row; i++){
        for(int j = 0; j < col; j++){
            b[j][i] = a[i][j];
        }
    }
    return b;
}
