trellis.fsm method invoked with polynomials

Hello, I have noticed that such a method ia available:

	//# Automatically generate the FSM from the generator matrix
	//# of a (n,k) binary convolutional code
	//######################################################################
	fsm::fsm(int k, int n, const std::vector<int>& G) I am doing some experimentation with BPSK31 code generation which uses Rate=1/2, Constraint length=5 convolutional code, polys are 0x17 and 0x19 now, k = 5 and n = 2, but how do I describe the polys in terms of array? I though, being poly1=0b10111 and poly2=0b11001, I had to specify them as a single array [1,0,1,1,1,1,1,0,0,1], but the comment talks about the generator matrix. Unluckily any attempt to specify a matrix returns error, and the C code seems to confirm an array is expected. any help? thank in advance matteo
