Detailed Description

template<int N, int M, typename T>
class QGenericMatrix< N, M, T >

The QGenericMatrix class is a template class that represents a NxM transformation matrix with N columns and M rows.

Since
4.6

The QGenericMatrix template has three parameters:

N Number of columns.
M Number of rows.
T Element type that is visible to users of the class.
