Details:

Implements the dcgain function for the control toolbox.

## Compute the DC gain k of a linear time invariant (LTI) system
##
## Transfer function for a continuous state space system (A,B,C,D)
## G(s) = C * inv(s*I - A) * B + D
##
## DC Gain: evaluate G(s) as s -> 0
## k = C * inv(-A) * B + D
##
## Transfer function for a discrete state space system (A,B,C,D,T)
## G(z) = C * inv(z*I - A) * B + D
##
## DC Gain: evaluate G(z) as z -> 1
## k = C * inv(I-A) * B + D
