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 !
