Detailed Description

Class for representing functions of 3 variables, supposed to be Cartesian coordinates $ f(x, y, z)$ .

()

It relies on a Chebyshev decomposition along all three coordinates, and an affine mapping for each one: e.g. $[-1,1] \to [\mathrm{xmin}, \mathrm{xmax}]$ .

Constructor & Destructor Documentation

◆ FuncSpec() [1/2]

Lorene::FuncSpec::FuncSpec	(	const string &	coord_name,
		const string &	field
	)

explicit

Constructor from files.

'coord_name' is a prefix for files containing coordinate data (coord_namex.dat, coord_namey.dat, coord_namez.dat); 'field', is the complete name of the file containing the field data.

◆ FuncSpec() [2/2]

Lorene::FuncSpec::FuncSpec ( const FuncSpec & )

Copy constructor.

◆ ~FuncSpec()

virtual Lorene::FuncSpec::~FuncSpec ( )

virtual

Destructor.
