Hello,
My question is about Simulink. I designed two systems: – 1. The first system computes an output A which is continuously integrated. The result is stored in B.
– 2. The second system takes A as an entry ("from workspace" block). A is continuously integrated. The result is stored in B2.
I used the same solver (ode4), same time step (4Hz), same initial conditions (0) for the integrator in system 1 and 2. Therefore B and B2 should be strictly equal…but there are differences (up to 10%) between them and I don't understand why. Any idea?
