sfaTimediff | R Documentation |
Calculates the first derivative of signal data
sfaTimediff(DATA, axType = "ORD1")
DATA |
The matrix of signals for which the derivative is calculated (one column per signal) |
axType |
Type of interpolation: "ORD1" (default) first order, "SCD" second ,"TRD" third, "ORD3a" cubic polynom |
matrix DATA
- DATA
contains the derivative signals, with the same structure as the input data.
setting axType to invalid values will lead to first order interpolation.
