Added matlab code samples.

All of these code samples currently are mis-identified in my repositories. I'm
donating them to the cause.

function Yc = plant(varargin)
% function Yc = plant(varargin)
%
% Returns the system plant given a number.
%
% Parameters
% ----------
% varargin : variable
% Either supply a single argument {num} or three arguments {num1, num2,
% ratio}. If a single argument is supplied, then one of the six transfer
% functions will be chosen from the list. If three arguments are chosen, a
% parallel sum of the two plants will be returned.
%
% Option 1
% --------
% num : integer, {1, 2, 3, 4, 5, 6}
% A number between 1 and 6 corresponding to the five plants.
% Option 2
% --------
% num1 : integer, {1, 2, 3, 4, 5, 6}
% A number between 1 and 6 corresponding to the five plants.
% num2 : integer, {1, 2, 3, 4, 5, 6}
% A number between 1 and 6 corresponding to the five plants.
% percent : double
% The percentage multiplier of the first plant. Should be between 0
% and 1. The percentage multiplier of the second plant will be 1 -
% percent.
%
% Returns
% -------
% Either a single plant or a parallel sum of scaled plants.
%
% Option 1
% --------
% Yc : transfer function
% 1 : 1 / s
% 2 : 1 / s(s + 1)
% 3 : 1 / s(s + 0.2)
% 4 : 10 / (s + 10)
% 5 : 5 / (s + 10)
% 6 : 10 / (s^2 +.2 * s)
%
% Option 2
% --------
% Yc : transfer function
% Yc = percent * Yc1 + (1 - percent) * Yc2, where Yc1 and Yc2 are plants
% from the list shown in Option 1.
