ParameterLib::Parameter< T > Struct Template Reference

Detailed Description

template<typename T>
struct ParameterLib::Parameter< T >

A Parameter is a function \( (t, x) \mapsto f(t, x) \in T^n \).

Where \( t \) is the time and \( x \) is the SpatialPosition. \( n \) is the number of components of \(f\)'s results, i.e., 1 for a scalar parameter and >1 for a vectorial or tensorial parameter.
