Method matrix/delay
DELAY overloads ao/delay for matrix objects.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: DELAY overloads ao/delay for matrix objects.
CALL: b = delay(a, pl)
b = delay(a, tau) % in this case, fft filtering is used
Time-series can be delayed either by an integer numbers of samples, or a
time, depending on the method chosen. For delaying by an explicit time,
you can use the fft filtering method, or a fractional delay filtering
method.
Parameters Description
EXAMPLES: 1) Shift by 10 samples and zero pad the end of the time-series
>> b = delay(a, plist('N', 10, 'method', 'zero'));
2) Shift by 0.1 seconds
>> b = delay(a, plist('mode', 'fftfilter', 'tau', 0.1));
