Estimate instantaneous bandwidth

specifies additional options for any of the previous syntaxes using name-value arguments.
You can specify the scale factor or the frequency limits used in the computation. For
example, `ibw`

= instbw(___,`Name,Value`

)`'FrequencyLimits',[10 20]`

computes the instantaneous bandwidth
of the input in the range from 10 Hz to 20 Hz.

`instbw(___)`

with no output arguments plots the
estimated instantaneous bandwidth.
