◆ accumulate_sensitivity()

procedure, pass(this) base_functional::base_functional_t::accumulate_sensitivity	(	class(base_functional_t), intent(inout)	this,
		class(design_t), intent(in)	design,
		type(time_state_t), intent(in)	time
	)

inherited

Normalised exactly as accumulate_value, so that the sensitivity stays consistent with the value it differentiates.

Parameters

this	The functional.
design	The design.
time	The current time state.

Definition at line 128 of file base_functional.f90.

◆ accumulate_value()

procedure, pass(this) base_functional::base_functional_t::accumulate_value	(	class(base_functional_t), intent(inout)	this,
		class(design_t), intent(in)	design,
		type(time_state_t), intent(in)	time
	)

inherited

Updates the value in place as the running mean of the function.

The result is the running mean of the function over the part of the functional's own time window that has been simulated so far, normalised by the length of time actually sampled. It is therefore invariant to the length of the run: extending end_time of the simulation past the functional's window leaves the value unchanged, and a windowed functional reports the mean over its window rather than over the run.

Parameters

this	The functional.
design	The design.
time	The current time state.
