2-D B-splines for STRUCTURED data

Constructor & Destructor Documentation

sierra::nalu::BSpline2D::BSpline2D	(	const int	order,
		const std::vector< double > &	indepVars1,
		const std::vector< double > &	indepVars2,
		const std::vector< double > &	depVars,
		const bool	allowClipping = true
	)

Construct a 2-D Bspline of the requested order.

Parameters

order	: Order of accuracy for interpolant (order-1 continuous derivatives)
indepVars1	: std::vector of independent variables in the first dimension
indepVars2	: std::vector of independent variables in the second dimension
depVars	: std::vector of dependent variables at each point on the mesh implied by indepVars1 and indepVars2, with fortran-style ordering (first dimension varies fastest)

double sierra::nalu::BSpline2D::value ( const double *  indepVar ) const

virtual

Evaluate the dependent variable via interpolation at the given value of the dependent variable.

Ordering is [x1,x2]

Implements sierra::nalu::BSpline.
