## Detailed Description

### template<typename _Tp>
class cv::Mat_< _Tp >

Template matrix class derived from Mat

The class Mat_ is a "thin" template wrapper on top of cv::Mat. It does not have any extra data fields, nor it or cv::Mat have any virtual methods and thus references or pointers to these two classes can be safely converted one to another. But do it with care, for example:

// create 100x100 8-bit matrix
Mat M(100,100,CV_8U);
// this will compile fine. no any data conversion will be done.
Mat_<float>& M1 = (Mat_<float>&)M;
// the program will likely crash at the statement below
M1(99,99) = 1.f;

While cv::Mat is sufficient in most cases, cv::Mat_ can be more convenient if you use a lot of element access operations and if you know matrix type at compile time. Note that cv::Mat::at<Tp>(int y, int x) and cv::Mat<_Tp>::operator ()(int y, int x) do absolutely the same thing and run at the same speed, but the latter is certainly shorter:

Mat_<double> M(20,20);
for(int i = 0; i < M.rows; i++)
for(int j = 0; j < M.cols; j++)
M(i,j) = 1./(i+j+1);
Mat E, V;
eigen(M,E,V);
cout << E.at<double>(0,0)/E.at<double>(M.rows-1,0);

It is easy to use Mat_ for multi-channel images/matrices - just pass cv::Vec as cv::Mat_ template parameter:

// allocate 320x240 color image and fill it with green (in RGB space)
Mat_<Vec3b> img(240, 320, Vec3b(0,255,0));
// now draw a diagonal white line
for(int i = 0; i < 100; i++)
img(i,i)=Vec3b(255,255,255);
// and now modify the 2nd (red) channel of each pixel
for(int i = 0; i < img.rows; i++)
for(int j = 0; j < img.cols; j++)
img(i,j)[2] ^= (uchar)(i ^ j); // img(y,x)[c] accesses c-th channel of the pixel (x,y)
