CC++一维数组的矩阵转置

// 矩阵转置
#include 

using namespace std;

// 二维数据
struct TD_Data
{
	double val_1;
	double val_2;
};

TD_Data* Matrix(const TD_Data* matrix, int size_r, int size_c, TD_Data* new_matrix)

	// 1.打印原数据
	int flag = 0;
	for (int i = 0; i < size_r * size_c; i++){
		cout << "(" << matrix[i].val_1 << ',' << matrix[i].val_2 << ')' << " ";
		flag++;
		if (flag == size_c) {
			cout << endl;
			flag = 0;
		}
	}

	// 2.转置
	for (int row = 0; row < size_r; row++)
	{
		for (int col = 0; col < size_c; col++)
		{
			new_matrix[col * size_r + row] = matrix[row * size_c + col];
		}
	}

	// 3.打印结果矩阵
	flag = 0;
