% This matlab function takes a column vector 
% y=(y(1),y(2))' and a scalar t as arguments,
% and returns a vector F(y,t)=(F(1),F(2))'
% where ' stands for transpose
% be aware that this sample function is
% similar to that is your hw assignment, but
% not identical

function v=F(y,t)
	
	v=zeros(2);

	v(1)=y(2);
	v(2)=(1-y(1))*y(2);
