Downsample data
resamplets is not recommended. Use timetable instead. For more information, see Convert Financial Time Series Objects fints to Timetables.
newfts = resamplets(oldfts,samplestep)
newfts = resamplets(oldfts,samplestep) downsamples the data
contained in the financial time series object oldfts every
samplestep periods. For example, to have the new financial time
series object contain every other data element from oldfts, set
samplestep to 2.
newfts is a financial time series object containing the same data
series (names) as the input oldfts.
