WebDescription. [h,w] = freqz (b,a,l) returns the frequency response vector h and the corresponding angular frequency vector w for the digital filter whose transfer function is determined by the (real or complex) numerator and denominator polynomials represented in the vectors b and a, respectively. The vectors h and w are both of length l.

Web18 jan. 2024 · I am making some homemade tools on Matlab. I made function that plot the frequency response of a discrete transfer function (just like freqz does). When I compare my result with the result from freqz, I get something very similar, but not exactly the same. Can somebody see why ? I am a little confused here.
