Hello, all: I am trying to solve a set of differential eqns . There is one problem that I don't know how to solve now. Let 's say I have x'(t)= ax(t)-by(t), y'(t)=c-x(t), when x(t) >d ( say a constant), x will be half of current value, but the odes still valid. How can I write the code the get the conditon? Thanks Sabrina
