Use dB as default for Bode plot?

[murrayrm]

Roberto Bucher suggests:

"bode" and "bode_plot": in my opinion the flag dB=True should be the
default choice (but this is only my opinion...)

This is obviously a matter of choice, but I agree that dB is the most commonly used convention. Karl Astrom and I chose not to use dB in our book since it often wasn't part of a students vocabulary in areas outside of electrical engineering (eg, biology or economics). The function use_matlab_defaults will set the default to use dB for Bode plots, if that helps.

There is stub code (currently commented out) in control/matlab.py that will call use_matlab_defaults and so using the matlab module would give plots compatible with matlab.

This has been fixed as of commit ebf8364 as part of PR #62. If you are using the MATLAB subpackage, the default units for Bode plots are in dB.
