How to calculate the computational complexity of filtfilt low-pass filter?

4 Ansichten (letzte 30 Tage)
I have a signal 'x' of length N which I perform lowpass filtering with matlab filtfilt. a and b are filter coefficients.
Is it possible to calculate its complexity in terms of Big O like O(...)?
y = filtfilt(b,a,x)

filtfilt just do twice (forward + backward) the filter. In your case it is IIR, where the complexity is
