Fit ODE graybox, how to access spline coefficients in MathScript RT

[EngrStudent]

I am trying to implement this:

I 'like' how it crushes the "textbook" shooting methods so unilaterally, and I want to try the spline version of the algo it is recommending.

If I am not going to homebrew the spline creation, which I would like not to do seeing as how there are built-ins to work with, then I'm going to need to access derivatives of the spline at points of interest without approximating them.  They should be analytic.

So how does one do access the "background" terms of something like poly_pwhermite using MathScript RT?

Sorry for the double post, but right now I am pulling "very near" points and using polyfit on it.  I would like something much less hacked than having to do such a thing.

If you insist on using Mathscript for this (why?), you should post in the Mathscript RT forum.

(I can move this thread if you want.)

People I work with are MatLab folks, and so it provides a basic interoperability while allowing me to still compile my code.

I didn't know there was one.  Thank you very much.

I copied this question to there just now, so if you like you can delete the one here.
