Detailed Description

Fourth-order interpolation in space.

Constructor & Destructor Documentation

◆ FourthOrderFineInterp() [1/2]

FourthOrderFineInterp::FourthOrderFineInterp ( )

Default constructor.

Object requires define() to be called before all other functions.

◆ ~FourthOrderFineInterp()

FourthOrderFineInterp::~FourthOrderFineInterp ( )

Destructor.

Destroys all objects created by define(). Passed in data references of define() are left alone.

◆ FourthOrderFineInterp() [2/2]

FourthOrderFineInterp::FourthOrderFineInterp ( const FourthOrderFineInterp & )

private
