Class ExplicitEuler

See sect. \ref findiff for details on the method.

In this implementation, the passed operator must be derived from either TimeConstantOperator or TimeDependentOperator. Also, it must implement at least the following interface:

typedef ... array_type;

// copy constructor/assignment
// (these will be provided by the compiler if none is defined)
Operator(const Operator&);
Operator& operator=(const Operator&);

// inspectors
Size size();

// modifiers
void setTime(Time t);

// operator interface
array_type applyTo(const array_type&);
static Operator identity(Size size);

// operator algebra
Operator operator*(Real, const Operator&);
Operator operator-(const Operator&, const Operator&);
