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。

函数

`aptknt`	Acceptable knot sequence
`augknt`	增强节点序列
`aveknt`	Provide knot averages
`brk2knt`	Convert breaks with multiplicities into knots
`chbpnt`	Chebyshev-Demko points
`knt2brk, knt2mlt`	Convert knots to breaks
`newknt`	New break distribution
`optknt`	Knot distribution “optimal” for interpolation
`sorted`	找到相对于网格站点的位置

Select and optimize knots using the optknt and newknt commands from Curve Fitting Toolbox™.

Use commands from Curve Fitting Toolbox™ to fit a spline to titanium test data with manual and automatic selection of knots.
