Hi everyone,

I've a small question about the interpolation on ALGLIB that confused me for a long time.

I don't know how to convert barycentricinterpolant to the coefficients like: y= ax^2+bx+c. I found this in the manual for polynomial/rational interpolation:

Quote:
// NOTE: result is returned as barycentricinterpolant structure.
// if you want to get representation in the power basis,
// you can use barycentricbar2pow() function to convert
// from barycentric to power representation (see docs for
// POLINT subpackage for more info).


Actually, I didn't find barycentricbar2pow() in interpolation.cpp, and I don't know how to display these coefficients.

Could you please give me a little suggestions?

Thanks a lot !
