find_settling_amplitude Function

public pure function find_settling_amplitude(x) result(rst)

Estimates the settling amplitude for a step response. The final-value estimate is the zero-frequency Fourier coefficient, $$x_f \approx \frac{1}{N}\sum_{k=0}^{N-1}x_k.$$

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(in),		dimension(:)	::	x	The step response of the system.

Return Value real(kind=real64)

The settling amplitude of the step response.
