三、部分源代码
function varargout = Turbo(varargin)
% set(handles.pushbutton25,'String',round(10*pos)/10);
%TURBO M-file for Turbo.fig
% TURBO, by itself, creates a new TURBO or raises the existing
% singleton*.
%
% H = TURBO returns the handle to a new TURBO or the handle to
% the existing singleton*.
%
% TURBO('Property','Value',...) creates a new TURBO using the
% given property value pairs. Unrecognized properties are passed via
% varargin to Turbo_OpeningFcn. This calling syntax produces a
% warning when there is an existing singleton*.
%
% TURBO('CALLBACK') and TURBO('CALLBACK',hObject,...) call the
% local function named CALLBACK in TURBO.M with the given input
% arguments.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
