A list,
Matlab GUI based inverted pendulum system
Ii. Source code
function varargout = pendulum(varargin)
% PENDULUM M-file for pendulum.fig
% PENDULUM, by itself, creates a new PENDULUM or raises the existing
% singleton*.
%
% H = PENDULUM returns the handle to a new PENDULUM or the handle to
% the existing singleton*.
%
% PENDULUM('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in PENDULUM.M with the given input arguments.
%
% PENDULUM('Property'.'Value',...). creates anew PENDULUM or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before pendulum_OpeningFunction gets called. An
% unrecognized property name orinvalid value makes property application % stop. All inputs are passed to pendulum_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
