Regarding the initial conditions in multiplication and addition when they are not at the same point: I think the best is(already discussed at ideas page) first to check if both the given holonomic functions are elementary function and calculate the initial conditions at a same point symbolicall

Thanks for your response Ondrej and Fredrik. I will soon be writing a wiki page for the algorithm. I agree with what Ondrej said, it's better to figure out the technical algorithms rather than abstracting the design. I am creating a class which can represent a holonomic function. Since we need

I looked at both the methods for addition algorithm( using Euclidean algorithm for computing LCLM, or making an ansatz and converting it into a linear system and then solving). But the Ore algebra method will also require a class representing rings and some basic functions like getting parent ri

I know it's a newbie question but I am stuck at it. In the paper mentioned in the ideas page http://www.risc.jku.at/publications/download/risc_2244/DIPLFORM.pdf the algorithm for addition of holonomic functions is described in Example 1.4.2, page 20. How do we get the linear system as mentioned
