bode magnitude response of fractional order system

How to plot bode magnitude response of a fractional order transfer function with Y axis to be linear not in db?

Answer 1

[Raj]

Use the command bodeplot instead of bode and set plot options using bodeoptions.

Here you have an option of setting your Magunits and Magscale to get linear plot instead of dB plot.

Get back in case you are having any difficulty.

[GOPAL SINGH]

in fractional order transfer function(fotf), I can't use command bodeplot. So, tell me how to use bodeoptions command using command bode.
