Best way to create a wrapper for C library for Continuous version of Tensor Train

Hello,

I would like to create a wrapper for the C library https://github.com/goroda/Compressed-Continuous-Computation that implements a low-rank approximation of multi-dimensional functions in the same spirit as ApproxFun.

Here is the arxiv paper:

Is there a Julia package to easily construct the wrapper?

Calling C functions is relatively “easy”. See e.g.

https://docs.julialang.org/en/v1/manual/calling-c-and-fortran-code/

and some JuliaCon talks, for example Huda Nassar’s workshop from JuliaCon 2020.

If you need to generate a lot of functions that look similar, you can automate this with metaprogramming.

Of course, you can also just port the library to Julia…

The link is also in the documentation above ( somewhere at the end)

Thank you @Tamas_Papp for mentioning this paper in ApproxFun for vector-valued function.
So far I have called the Python wrapper c3py of the C library in Julia and its working well. But I want to avoid wrapper of a wrapper and I need to add a few functions.
