# bodeplot

Plot Bode frequency response with additional plot customization options

## Syntax

## Description

`bodeplot`

lets you plot the Bode magnitude and phase of a
dynamic system model with a broader range of plot customization options than
`bode`

. You can use `bodeplot`

to obtain the plot handle
and use it to customize the plot, such as modify the axes labels, limits and units. You can
also use `bodeplot`

to draw a Bode response plot on an existing set of axes
represented by an axes handle. To customize an existing Bode plot using the plot
handle:

Obtain the plot handle

Use

`getoptions`

to obtain the option setUpdate the plot using

`setoptions`

to modify the required options

For more information, see Customizing Response Plots from the Command Line. To create Bode plots with default options or to
extract the frequency response data, use `bode`

.

plots
the Bode magnitude and phase of the dynamic system model
`h`

= bodeplot(`sys`

)`sys`

and returns the plot handle `h`

to the plot. You
can use this handle `h`

to customize the plot with the `getoptions`

and `setoptions`

commands. If `sys`

is a multi-input,
multi-output (MIMO) model, then `bodeplot`

produces a grid of Bode plots,
each plot displaying the frequency response of one I/O pair.

plots the Bode frequency response with the options set specified in
`h`

= bodeplot(___,`plotoptions`

)`plotoptions`

. You can use these options to customize the Bode plot
appearance using the command line. Settings you specify in `plotoptions`

overrides the preference settings in the MATLAB^{®} session in which you run `bodeplot`

. Therefore, this syntax
is useful when you want to write a script to generate multiple plots that look the same
regardless of the local preferences.

plots system responses for frequencies specified by the frequencies in
`h`

= bodeplot(___,`w`

)`w`

.

If

`w`

is a cell array of the form`{wmin,wmax}`

, then`bodeplot`

plots the response at frequencies ranging between`wmin`

and`wmax`

.If

`w`

is a vector of frequencies, then`bodeplot`

plots the response at each specified frequency.

You can use `w`

with any of the input-argument combinations in
previous syntaxes.

See `logspace`

to generate logarithmically spaced
frequency vectors.
