Sliding Sum Averaging Filter (Moving Average)

Description

Moving average filter implemented using a "Sliding Sum" technique. Comparatively efficient.

Usage:

Smoothed Data = slidefilter(Data Vector, Sliding Interval Length in Samples)

• MATLAB release: MATLAB 7.0.4 (R14SP2)

[Duane Hanselman]

This function is poorly described. Perhaps an simple example would demonstrate its potential usefulness. As it is, the algorithm can only be understood by looking at the code itself. How is this "more efficient" than a moving average filter? What is meant by "efficient"? Edges are treated differently than what? Why must data be limited to 1-D? Why clear two scalar values within the function? Doing so does not save time or memory. What is meant by "the output will be normalized"?

[Jos van der Geest]

Unfortunately, slidefilter (as <movave> by the same author) introduces some small floating point errors.
The help is quite poor (see Duane's comments).
