Resample time-domain data by decimation or interpolation (requires Signal Processing Toolbox software)
resample(data,P,Q) resamples data such
that the data is interpolated by a factor
then decimated by a factor
in decimation by a factor
resample(data,P,Q,order) filters the data
by applying a filter of specified
interpolation and decimation.
Name of time-domain
iddata object. Can be
input-output or time-series data.
Data must be sampled at equal time intervals.
Integers that specify the resampling factor, such that the new
sample time is
Q/P times the original one.
(Q/P)>1 results in decimation and
Order of the filters applied before interpolation and decimation.
