xcorrTD takes two discrete time signals as input and calculates cross-correlation values, cross-correlation
coefficients and delay (lag) between two signals. The computation is performed in the time domain. The results of xcorrTD has been validated against the MatLAB's xcorr function.
For cross-correlation in frequency domain see xcorrFD.
Syntax: [lags,ck,cc,td] = xcorrTD(x,y)
x = input signal 1 (must be a Nx1 or 1xN vector)
y = input signal 2 (must be a Nx1 or 1xN vector)
lags = a vector of lags with a length of 2xN-1 (N = number of
data points in signal x or y)
ck = cross-correlation values (MatLAB xcorr gives them as
cc = correlation coefficients
td = delay (i.e., number of lags) between two signals
