Hello,
In the chapter about polynomial interpolation, how can one use the algorithm, so that given an ordinate y, one can get the first abscissa x such that f(x)=y using the polynomial?
Obtain the interpolating polynomial coefficients first, and then use Newton-raphson root finding algo? Or is there a more inherent way?
Same for cubic splines?
rds,
