+    \class QGenericMatrix
+    \brief 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 four parameters:
+
+    \table
+    \row \i N \i Number of columns.
+    \row \i M \i Number of rows.
+    \row \i T \i Element type that is visible to users of the class.
+    \row \i InnerT \i Element type that is used inside the class.
+    \endtable
+
+    Normally T and InnerT are the same type; e.g. float or double.
+    But they can be different if the user wants to store elements
+    internally in a fixed-point format for the underlying hardware.
