The Ackermann function, due to its definition in terms of extremely deep recursion, can be used as a benchmark of a compiler's ability to optimize recursion. The first use of Ackermann's function in this way was by Yngve Sundblad, The Ackermann function. A Theoretical, computational and formula manipulative study.

Equation is the characteristic equation of the plant+control law.7.4.1 Pole Placement. We will use the method of pole placement; since our control law has n unknown parameters (the K i), we are able to place the n closed-loop poles (eigenvalues) arbitrarily.
