Time derivative of input signal, specified as a real scalar or vector. The input signal is differentiated with respect to time as: y ( t) = Δ u Δ t = u ( t) − u ( T p r e v i o u s) t − T p r e v i o u s | t > T p r e v i o u s, where t is the current simulation time and T p r e v i o u s is the time of the last output time of the simulation.
