Re: [python-control-discuss] Kalman or LQG

[Richard M. <mu...@cd...>]

Neither lag() or kalman() are currently implemented.  In the link you sent, these are *not* marked with a star (=> not implemented).  The legend for entries (at the top of the page) is:

* : The feature is currently implemented.
- : The feature is not planned for implementation.
s : A similar feature from an other library (Scipy) is imported into the module, until the feature is implemented here.

We should perhaps add to to this:

  : The feature is not yet implemented
~ : A prototype of the function is available, but with limited functionality

For lqg() and kalman, the status is ' ' (empty) => nobody has yet implemented this.

Since all that is required to implement these functions is (roughly) solving some Riccati equations and do some system manipulations (all of which are already in the current release), it shouldn't be
