Detailed Description

template<typename _Tp>
class cv::MatCommaInitializer_< _Tp >

Comma-separated Matrix Initializer.

The class instances are usually not created explicitly. Instead, they are created on "matrix << firstValue" operator.

The sample below initializes 2x2 rotation matrix:

double angle = 30, a = cos(angle*CV_PI/180), b = sin(angle*CV_PI/180);
Mat R = (Mat_<double>(2,2) << a, -b, b, a);
