两种用自定义数据初始化Mat

using namespace std;

//方法一
cv::Matx33f m(1,2,3,   //采用定义好的矩阵3*3的
9,9,9,
5,2,9);
Mat mat1(m);
cout<<mat1<<endl;
//方法二
Matx<uchar,50,50>mat2(1,2,3);   //采用自定义的50*50的uchar类型的矩阵
Mat mat(mat2);  //转换为Mat类型
cout<<mat2<<endl;
//方法三
uchar m3[3][3]={0,1,2,3};  //采用自定义矩阵
Mat mat3=Mat(3,3,CV_8U,m3);
cout<<mat3<<endl;
getchar();
waitKey(0);
return 0;
