Calculus / ODE's

[Peter]

Hi all,

I'm using LabView 6.0 and the supplied routines.

Mathematics -> Calculus -> Differential Equations ->
* ODE Runge Kutta 4th Order
* ODE Cash Karp 5th Order

For some simulation work. These are very good and supprisingly
flexible but I need something that works a bit better on "Stiff" sets
of ODE problems.

1) Does Labview V6.1 offer more Differential Equation routines than
V6.0? If so what ones?

2) Does any one sell/provide more advanced Differential Equations
routines, such as the "Bulirsch-Stoer", "Bader-Deuflhard" and other
predictor-corrector methods (Gear, Shampine and Gordon) ?

Thanks,

Peter

Peter,

Concerning your first question,Labview V6.1 does not offer more Differential Equation routines than V6.0.

For the second question, I don't know if there are such libraies available. Perhaps somebody on the forum will be able to help you out. I've been looking around and didn't find anything except for a white paper that shows programming PDE in the G environment.
