Solve equation, specified by cubic spline.
Given f(x) function, scpecified by spline coefficients and reference
points (see
eval_spline_factors ), and y value, this function finds such x
that f(x)=y. Solving performed using iteration method. No dead-cycle checks performed.
For parameters description refer to
build_spline .
