[python-control-discuss] Any reason for the behavior of matlab.initial ?

[Rene v. P. <ren...@gm...>]

Hi,

Just had a student confused with the behavior of initial in the module
control.matlab. Looking at the help:

initial(sys, T=None, X0=0.0, input=0, output=0, **keywords)
    Initial condition response of a linear system

    If the system has multiple inputs or outputs (MIMO), one input and one
    output have to be selected for the simulation. The parameters `input`
    and `output` do this. All other inputs are set to 0, all other outputs
    are ignored.

I think the part about inputs is complete bull, since they don't play a
role in initial condition response. Is there any reason to select only a
single output?

If there are no objections, I will update this one, and make it a bit more
in line with the one in Matlab (R)

Greetings,

René
