C++实现卷积运算

清理磁盘，看到了几年前的代码

#include<iostream>
using namespace std;
void main()
{
	//输入卷积矩阵

	int row1 = 3, col1 = 3;
	int a[3][3];
	//cout<<"输入卷积矩阵的行数：";
	//cin>>row1;
	//cout<<"输入卷积矩阵的列数：";
	//cin>>col1;
	cout << "输入卷积矩阵：" << endl;

	for (int i = 0; i < row1; i++)
		for (int j = 0; j < col1; j++)
		{
			cin >> a[i][j];
		}
	//输入卷积核
	int row2 = 2, col2 = 2;
	int b[2][2];
	/*cout<<"输入卷积核矩阵的行数：";
	cin>>row2;
	cout<<"输入卷积核矩阵的列数：";
	cin>>col2;  */
	cout << "输入卷积核矩阵：" << endl;

	for (int i = 0; i < row2; i++)
		for (int j = 0; j < col2; j++)
		{
			cin >> b[i][j];
		}
	//进行卷积
	int c[3][3] = { 0,0,0,0,0,0,0,0,0 };
	for (int i = 0; i < row1; i++)
		for (int j = 0; j < col1; j++)
		{
			int p = i, q = j;
			for (int k = 0; k < row2 && p < row1; k++, p++)
				for (int m = 0; m < col2 && q < col1; m++, q++)
					c[i][j] = c[i][j] + a[p][q] * b[k][m];//定义b[0][0]为卷积中心
		}
	for (int i = 0; i < row1; i++)
	{
		for (int j = 0; j < col1; j++)
		{
			cout << c[i][j] << " ";
		}
		cout << endl;
	}
}
