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

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.
