[−][src]Function filter::gh::critical_damping_parameters_order_three
pub fn critical_damping_parameters_order_three<T: FloatCore>(
theta: T
) -> (T, T, T)
Computes values for g, h and k for a critically damped filter. The idea here is to create a filter that reduces the influence of old data as new data comes in. This allows the filter to track a moving target better. This goes by different names. It may be called the discounted least-squares g-h filter, a fading-memory polynomal filter of order 1, or a critically damped g-h filter.
