I'm using the ODE
Cash Karp for some simulation routines and I'm wishing/hoping I can get this
system to run faster (P4 1.6; 1gig ram; WinXP, LabVIEW 7.0). Currently, to
simulate 1 sec worth of data takes ~80 sec. I've tried some of the other
ODE solvers and they don't simulate my system well so if I stay with LabVIEW,
I'm stuck with the Cash Karp. Does anyone know if the ODE routines have
been optimized with the new version of 7.1? Does anyone out there have
knowledge if a MatLab (or MathCad) routine would perform this calculation
quicker? I have done the "simplify the equation" to see if the routine
runs any faster, but that had no effect.
