Estimate instantaneous frequency

specifies additional options for any of the previous syntaxes using name-value
pair arguments. You can specify the algorithm used to estimate the instantaneous
frequency or the frequency limits used in the computation.`ifq`

= instfreq(___,`Name,Value`

)

`instfreq(___)`

with no output arguments plots
the estimated instantaneous frequency.
