Class template `Dune::XT::Functions::ExpressionFunction`¶

Inherits from Dune::XT::Functions::FunctionInterface.

template<size_t d, size_t r, class RangeField> class Dune::XT::Functions::ExpressionFunction : public FunctionInterface<d, r, 1, RangeField>¶: Scalar- and vector-valued (rC == 1) specialization of ExpressionFunction.

template<> Dune::XT::Functions::ExpressionFunction::ExpressionFunction<d, r, 1, RangeField>(const std::string &variable, const Common::FieldVector<std::string, r> &expressions, const Common::FieldMatrix<std::string, r, d> &gradient_expressions, const size_t ord, std::string nm = static_id())¶

Creates an Expression function

This constructor just expands expressions and gradient_expressions from a Common::FieldVector and Common::FieldMatrix to ExpressionStringVectorType and GradientStringVectorType, respectively.

For instance, if d = 2 and r = 1 and expression = {“x[0]*x[1]”}, gradient should be {“x[1]”,“x[0]”}. For r = 2 we have for example the expression = {“sin(x[0])”, “x[1]*x[1]”} with the gradient .

template<> Dune::XT::Functions::ExpressionFunction::ExpressionFunction<d, r, 1, RangeField>(const std::string &variable, const Common::FieldVector<std::string, r> &expressions, const size_t ord, std::string nm = static_id())¶: ExpressionFunction without given gradient
