Detailed Description

Base class for 2d interpolation.

Provides an interpolation of a function defined at mesh points (x,y), where 0 <= (x,y) <= 1.

Constructor & Destructor Documentation

Interpolation2D()

Interpolation2D::Interpolation2D ( size_t  n, size_t  m, const std::vector< double > &  f  )

protected

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.

~Interpolation2D()

virtual Interpolation2D::~Interpolation2D ( )

inlinevirtual

Virtual destructor.

Member Function Documentation

operator()()

virtual double Interpolation2D::operator() ( double  x, double  y  ) const

pure 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.

Implemented in BiCubicInterpolation2D, BiLinearInterpolation2D, and ClosestInterpolation2D.
