A spline is a series of polynomial functions joined at intervals called knots or breaks.
Use Curve Fitting Toolbox™ functions to determine the locations of the knots that optimize interpolation.
|Acceptable knot sequence|
|Augment knot sequence|
|Provide knot averages|
|Convert breaks with multiplicities into knots|
|Good data sites, Chebyshev-Demko points|
|Convert knots to breaks and their multiplicities|
|New break distribution|
|Knot distribution “optimal” for interpolation|
|Locate sites with respect to mesh sites|
