Details:
Hello,
I have noticed that the acker function is accepting on its third input
argument (vector of desired poles) a vector with any size. The size of this
argument should be of the same size as the dimension of the first argument
(dynamic matrix A).
This behavior is not present on MATLAB. There if a vector of different size is
used the function gives a error statement. See below an example of the wrong
behavior:
A = [1 20; 5 7];
B = [1; 0;];
C = [0 1];
D = 0;
poles = [-1 -2 -3 -5];
K = acker(A,B,poles)
The vector K obtained does not make sense. It was expected an error message
