inconsistent kwarg klist/kvect/gains in rlocus doc about python-control

[gdmcbain]

This is miscalled in pymoca/pymoca test/notebooks/Spring,ipynb:

    "control.rlocus(ss[0,0], klist=pl.logspace(-2,1,1000));\n",

[bnavigator]

The first line of the docstring for rlocus suggests that there's a kwarg klist,

Only for the MATLAB wrapper though. The MATLAB docs call the parameter k by the way.
Using a MATLAB wrapper with a python kwarg is somehow unusual.

PR welcome.

This is miscalled in pymoca/pymoca test/notebooks/Spring,ipynb:

The MATLAB wrapper is not part of that call. The kwarg for control.rlocus has been kvect for 13 years: 8ebb73b.

Ah, yes, sorry I see now that control.rlocus doesn't call control.matlab.wrappers.rlocus at all but rather control.root_locus_plot; I had overlooked this:

python-control/control/rlocus.py

Line 452 in e4a03e8

rlocus = root_locus_plot

My real problem was pymoca/pymoca#324 so I'll look over there at fixing that. I'm not presently concerned with control.matlab, but I'll turn in the PR as requested, while I'm at it.
