Function File: k = acker (A, b, p)

Calculates the state feedback matrix of a completely controllable SISO system using Ackermann’s formula

Given the state-space system

      .
      x = Ax + bu

and the desired eigenvalues of the closed loop in the vector p, the state feedback vector k is calculated in the form

      k = (k1 k2 ... kn)

such that the closed loop system matrix

      A - bk

has the eigenvalues given in p.
