saefilter

SAE class filter.

Syntax

saefilter(indep_vec, dep_vec, class)

Argument

indep_vec
The independent vector of the curve to be filtered.
dep_vec
The dependent vector of the curve to be filtered.
class
The SAE class of the filter (typically 60, 180, 600, 1000).

Example

Curve Math Vectors Results
x = c1.x

y = saefilter(c1.x, c1.y, 60)

 The original curve filtered by an SAE class 60 filter.

Comments

indep_vec and dep_vec must be vectors with the same number of elements. class must be a scalar with a non-negative value. The result is a vector with the same number of elements as indep_vec. The result is obtained by low-pass filtering dep_vec using a filtering function defined by the SAE class.

If the sampling frequency is less than 3.2 * class, the curve is unfiltered.
