sfaTimediff {rSFA}

Calculates the first derivative of signal data

Description

Calculates the first derivative of signal data

Usage

sfaTimediff(DATA, axType = "ORD1")

Arguments

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

Value

matrix DATA
- DATA contains the derivative signals, with the same structure as the input data.

Note

setting axType to invalid values will lead to first order interpolation.
