freqresp
Frequency response of rational object and rationalfit
function
object
Description
[
calculates the frequency response, response
, outputfreq
] = freqresp(fit
,inputfreq
)response
of the fit
of a rationalfit
function object or a rational
object
at the specified input frequencies, inputfreq
.
Note
There is limited control over how the freqresp
function
extrapolates outside the input data's frequency band because the
rational
object creates a rational-function fit to frequency-domain
data . The high-frequency limit of the response is determined by the
TendsToZero
property of the rational
object: if
the TendsToZero
is set to true, the response will approach zero at
high frequencies; otherwise, it will follow the best-fitting that is predicted by the
rational
object.
