Detailed Description

1D smooth spline curve with weights for provided nodes. Number of nodes should be > 3

Member Typedef Documentation

typedef std::vector<Coeffs> USmspl3Curve1d::CoeffsAr

protected

Smoothing parameter.

Constructor & Destructor Documentation

USmspl3Curve1d::USmspl3Curve1d

(

double

alpha = 0

)

Empty curve with default smoothing parameter.

USmspl3Curve1d::USmspl3Curve1d	(	const Nodes &	nodes,
		double	alpha = 0.
	)

Construct curve width provided nodes and smoothing parameter.

virtual USmspl3Curve1d::~USmspl3Curve1d ( )

virtual

Destructor.

Member Function Documentation

virtual void USmspl3Curve1d::addNode ( const Node &  node, int  id  )

inlinevirtual

Add new point to the curve at index = id. If id < 0 or out of range then add new last point.

virtual void USmspl3Curve1d::approximate ( const Nodes &  nodes, double  alpha = 0.  )

virtual

General approximation method.

bool USmspl3Curve1d::calc_coeffs ( const Nodes &  nodes, double  alpha, CoeffsAr &  coeffs  )

protected

Calculate spline coefficients

double USmspl3Curve1d::get_s ( double  p ) const

inlineprotected

Calculates spline on corresponded segment

virtual double USmspl3Curve1d::operator() ( double  p ) const

virtual

Get curve value for provided argument.

virtual bool USmspl3Curve1d::ready ( ) const

inlinevirtual

True if spline constructed and object is ready to approximate.

virtual bool USmspl3Curve1d::removeNode ( size_t  id )

inlinevirtual

Remove node with provided id. Return false on error.
