Computer Vision with OpenCV 3 and Qt5

Matx< _Tp, m, n >

The Matx class is only used in case of <indexentry content="Mat class:Matx class" dbid="256603" state="mod"> small matrices which have a known type, width, and height at compile time. It has methods similar to Mat and provides matrix operations, again like Mat. In general, you can use the same Mat class that you just learned about instead of Matx, since it provides more flexibility and functions to work with.
