WebFor example, if y [i] starts at some nonzero value, but in time decays to zero, then pure relative error control on y [i] makes no sense (and is overly costly) after y [i] is below some noise level. Then abstol (if scalar) or abstol [i] (if a vector) needs to be set to that noise level. Web29 okt. 2012 · Problems with simulation DCMotor example wont simulate- Missing kinsol_initialization?
