Description:
|
Estimates a fit tolerance for interpolating the given set of initial points. It takes an initial value from the
fitol_curve_interp option if this is positive, otherwise it starts with
SPAresfit. Then it estimates the maximum curvature by fitting a circle to each consecutive set of three points, and, if necessary reduces the fit tolerance to an order of magnitude smaller than the corresponding minimum radius of curvature. As a sanity check, it never returns less than
SPAresabs.
|
|
|
If
fit_tol been set in the
fitol_curve_interp option, that is used as a starting value, otherwise
opt_tol is used if supplied. Otherwise the starting value is
SPAresfit.
