I have an interpolating function in Mathematica from solving a complicated differential equation. I want to then use the interpolating function directly in my other program, which is written in C++. Is there any possible way to export the interpolating function over?

My first solution was to just export a table of values of the interpolating function, and then re-interpolate it in C++, but that seems very slow and roundabout, especially because I will have to do this multiple times.

Answers to How to make use of an interpolating function outside of Mathematica? and Interpreting the interpolating function and saving data to plot with external program show how to extract either the piecewise polynomials, or the grid and numerical data, depending on what you want to do with your results afterwards. Also look at this answer for a method to extract values straight from InterpolatingFunction. – MarcoB Oct 02 '22 at 21:40
