This concept specifies the interface a controlled stepper has to fulfill to be used within integrate functions.
A controlled stepper following this Controlled Stepper concept provides the possibility to perform one step of the solution x(t) of an ODE with step-size dt to obtain x(t+dt) with a given step-size dt. Depending on an error estimate of the solution the step might be rejected and a smaller step-size is suggested.
The type characterizing the state of the ODE, hence x.
The type characterizing the derivative of the ODE, hence d x/dt.
The type characterizing the dependent variable of the ODE, hence the time t.
numerical data type which is used within the stepper, something like
