Steady-State Filter

This document provides a detailed discussion of the input and output parameters and their usage in the steady-state filter implementation. The input parameters are as follows:

- x0 initial state vector: A vector containing initial state information, typically used to initialize the filter's state variables in algorithms like Kalman filtering or exponential smoothing.

- smoocof ideal smoothing coefficient: This parameter serves as a weighting factor for calculating smoothed positions, often implemented using exponential smoothing algorithms where it controls the balance between previous estimates and new measurements.

- inp position measurement array: An array containing all measured position data, which serves as the primary input for the filtering algorithm and is typically processed sequentially in implementation.

- npts number of points in input positions: This parameter specifies the total number of data points in the position measurement array, determining the iteration count in the filtering loop structure.

- T sampling interval: The time interval between consecutive position measurements, crucial for discrete-time filter implementations where it affects state transition calculations and velocity estimation.

- nvar ideal noise variance: This parameter is used for calculating measurement errors and is essential in statistical filtering approaches for optimizing the filter's gain and uncertainty propagation.

The output parameters include:

- residual position error array (residuals): This array contains the differences between measured positions and predicted positions, commonly used for filter performance validation and innovation sequence analysis in adaptive filtering implementations.

- estimate predicted position array: This array contains the filtered position information calculated based on the input parameters, representing the algorithm's optimal estimation output after processing all measurements through the filtering algorithm.
