Analog Domain
freqs
evaluates frequency response for an analog filter defined by two input coefficient vectors, b
and a
. Its operation is similar to that of freqz
; you can specify a number of frequency points to use, supply a vector of arbitrary frequency points, and plot the magnitude and phase response of the filter.
