Template class for small matrices whose type and size are known at compilation time.
If you need a more flexible type, use Mat . The elements of the matrix M are accessible using the M(i,j) notation. Most of the common matrix operations (see also MatrixExpressions ) are available. To do an operation on Matx that is not implemented, you can easily convert the matrix to Mat and backwards:
4, 5, 6,
7, 8, 9);
cout <<
sum(Mat(m*m.t())) << endl;
Except of the plain constructor which takes a list of elements, Matx can be initialized from a C-array:
float values[] = { 1, 2, 3};
In case if C++11 features are available, std::initializer_list can be also used to initialize Matx:
