I am trying to use "place" to determine an observer matrix L from the desired closed loop poles. I am getting an error "??? Error using ==> place at 172
The "place" command could not place the poles at the specified locations. Probable
causes include:
* (A,B) is nearly uncontrollable
* The specified locations are too close to each other.

Error in ==> assignment1 at 61
Observerm = place(A',C',observerpoles)'

Any help would be appreciated

my guess, which is just a whild guess is that your A,B are
nearly uncontrollable or that the specified locations are
too close to each other.
