Functions
std::vector< double >	kynema::math::MapGeometricLocations (std::span< const double > geom_locations)
	Maps input geometric locations -> normalized domain using linear mapping.
std::vector< std::vector< double > >	kynema::math::ComputeShapeFunctionValues (std::span< const double > input_points, std::span< const double > output_points)
	Computes shape function matrices ϕg relating points ξb to ξg At least two input points are required and it is assumed that there are more output points than input points.
std::vector< std::vector< double > >	kynema::math::ComputeShapeFunctionDerivatives (std::span< const double > input_points, std::span< const double > output_points)
	Computes shape function derivatives dϕg relating points ξb to ξg At least two input points are required and it is assumed that there are more output points than input points.
std::vector< std::array< double, 3 > >	kynema::math::PerformLeastSquaresFitting (size_t p, std::span< const std::vector< double > > shape_functions, std::span< const std::array< double, 3 > > points_to_fit)
	Performs least squares fitting to determine interpolation coefficients.
