R Documentation
Correction for warping coefficients when using zeropadding
Description
This function calculates the warping coefficients for the
original range of the data, based on the warping of zero-filled
data. Only needed when zeros are added in the beginning of the signal.
Usage
calc.zerocoef(coef, zeros)
Arguments
coef
vector of warping coefficients of a PTW-calculation on a
set of signals with zeros added to the beginning of the signal
zeros
the number of zeros added
Value
a vector containing the corrected warping coefficients
