% PLANT_MODEL4PID M-file for plant_model4pid.fig
%      PLANT_MODEL4PID, by itself, creates a new PLANT_MODEL4PID or raises the existing
%      singleton*.
%
%      H = PLANT_MODEL4PID returns the handle to a new PLANT_MODEL4PID or the handle to
%      the existing singleton*.
%
%      PLANT_MODEL4PID('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PLANT_MODEL4PID.M with the given input arguments.
%
%      PLANT_MODEL4PID('Property','Value',...) creates a new PLANT_MODEL4PID or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before plant_model4pid_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to plant_model4pid_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
