double operator()(const double &x) const ecl_assert_throw_decl(StandardException)
Access the value of the spline function at the specified value.
#define LOC
Template wrapper for a generic spline function.
Array< double, 2 > time_domain
#define ecl_assert_throw(expression, exception)
OutOfRangeError
#define ecl_assert_throw_decl(exception)
double dderivative(const double &x) const ecl_assert_throw_decl(StandardException)
Access the value of the spline function&#39;s 2nd derivative at the specified value.
double derivative(const double &x) const ecl_assert_throw_decl(StandardException)
Access the value of the spline function&#39;s derivative at the specified value.
SplineFunction(const double &time_begin, const double &time_end, const Function &f)
Constructor, copies across an already existing spline function type and wraps it. ...
const Array< double, 2 > & domain()
Get access to the domain for this spline function.
This is a parent class for generic spline functions.
