断点、节点和位点
优化节点和断点
样条是在称为节点或断点的区间处联接的一系列多项式函数。
使用 Curve Fitting Toolbox™ 函数确定优化插值的节点的位置。

brk2knt | Convert breaks with multiplicities into knots |
chbpnt | Chebyshev-Demko points |
knt2brk, knt2mlt | Convert knots to breaks and their multiplicities |
newknt | New break distribution |
optknt | Knot distribution “optimal” for interpolation |
