Detailed Description

BiCubic 2d interpolation.

Calculates the derivatives of the function at mesh points using central finite differences. Zero derivatives are assumed at boundaries.

Constructor & Destructor Documentation

BiCubicInterpolation2D()

BiCubicInterpolation2D::BiCubicInterpolation2D	(	size_t	n,
		size_t	m,
		const std::vector< double > &	f
	)

Constructor.

Makes an independent object for interpolation of data. An internal copy of f is created. Data mesh is assumed to be accessed with indexing i+j*n.

~BiCubicInterpolation2D()

virtual BiCubicInterpolation2D::~BiCubicInterpolation2D ( )

inlinevirtual

Destructor.

Member Function Documentation

operator()()

double BiCubicInterpolation2D::operator() ( double  x, double  y  ) const

virtual

Operator for getting interpolation at (x,y).

Returns an interpolated value of the function at (x,y), where 0 <= (x,y) <= 1. Returns NaN outside this area.

Implements Interpolation2D.
