It's my understanding that the typemap for MatrixF* will only be used if your function declaration has a parameter of type MatrixF*. On the other hand, if the function declaration uses MatrixF*, then SWIG will use the MatrixF* typemap if it exists, otherwise it will use the Matrix* typemap if it exists.
