%计算出str1的值给njieguo1=n/180*pi; %把n变为多少πm=sin(jieguo1);%得出正弦值str2=num2str(m);%把m变为字符型jieguo=strcat(str4,str2);%把str4和str2合并为jieguoset(handles.edit1,'string',jieguo);%把合并后的字符串重新付给edit,作为结果显示器的字符else%如果第一个字符就是数字jieguo1=eval(string);%计算出string的值给jieguojieguo2=jieguo1/180*pi;%把jieguo变为多少πjieguo=sin(jieguo2);%得出正弦值set(handles.edit1,'string',jieguo);%把合并后的字符串重新付给edit,作为结果显示器的字符end而按键'cos,tan'同按键'sin'的大致一样。而'cos，tan,sin-1,cos-1,tan-1'按键也大致一样，只是'tan-1'中的值可以大于1,而'sin-1,cos-1'中的值要小于1。其实'1/x,ln,log,x^2,%,e^x,10^x,x^1/2'都大致一样，只是在其中添加了各自所需计算的函数程序而已。3.3.4接下来是‘AC，DEL，=’函数的程序编制AC按键：在functionpushbutton36_Callback(hObject,eventdata,handles)后面添加set(handles.edit1,'string','');即可。DEL按键：在functionpushbutton37_Callback(hObject,eventdata,handles)后添加string=get(handles.edit1,'string');%得到显示器edit的字符串ss=char(string);%把string变为字符型l=length(ss);%得到ss的字符长度set(handles.edit1,'string',ss(1:l-1));%把ss的1到l-1个字符给显示器edit，即删除最后一个字符。=按键：在functionpushbutton38_Callback(hObject,eventdata,handles)后添加string=get(handles.edit1,'string');%得到显示器edit的字符串jieguo=eval(string);%计算string的值set(handles.edit1,'string',jieguo);%把计算值给edit,作为结果显示器的字符。最后运行后就得到如下界面：（可以运算）函数命令设计过程打开file-M-file输入hf=figure('Color',[1,1,1],'Position',[100,200,600,450],...'Name','科学计算器','NumberTitle','off','MenuBar','none');he=uicontrol(hf,'Style','Edit','Units','normalized',...'Position',[0.2,0.88,0.6,0.1],'Back',[1,1,1],'Horizontal','right');h1=uicontrol(hf,'Style','Push','Units','normalized',...'Position',[0.25,0.78,0.06,0.06],'Horizontal','center',...'String','sin','back',[0.67,0,1],'Call','m1');……..h36=uicontrol(hf,'Style','Push','Units','normalized',...'Position',[0.65,0.08,0.07,0.07],'Horizontal','center',...'String','/','Back',[0.67,0,1],'Call','m36');然后运行得到如下界面：可以看出一共有36个按键，就有36个’call’，在M-file中编写36个M-file函数，如：string=get(he,'string');k=find(string=='+'|string=='-'|string=='*'|string=='/'|string=='(');u=max(k);ifu>=2str4=string(1:u);str1=string(u+1:end);n=eval(str1);jieguo1=n/180*pi;m=sin(jieguo1);str2=num2str(m);jieguo=strcat(str4,str2);set(he,'string',jieguo);elseifstring(u)=='('str4=string(u);str1=string(u+1:end);n=eval(str1);jieguo1=n/180*pi;m=sin(jieguo1);str2=num2str(m);jieguo=strcat(str4,str2);set(he,'string',jieguo);elsejieguo1=eval(string);jieguo2=jieguo1/180*pi;jieguo=sin(jieguo2);set(he,'string',jieguo);end就保存在m1.m中，在科学计算器运行时，当点击到’sin’按键时就会调用m1.m中的函数，其他按键以此类推一共有m1.m到m36.m，函数程序和GUI设计函数程序大致相同，在此不一一列举了。5.不足之处在清屏后不能再显示器edit中显示‘0.’。没有做到更人性化，还是有点不美观。在函数命令设计中我们不能把界面做的和GUI设计的一致，如按键上的字符串的字体颜色，按键颜色等。(四)函数命令程序太过繁琐。（五）实现科学计算器的功能太少。6.总结此次的课程实际，是针对MTLAB课程进行的，在平时的学习当中，我们了解了软件所具有的很多功能。在不断的操作中熟悉所了解的知识，每次的上机实验是实践的主要部分。通过这次设计，再次在实践中学习。团队合作，运用自身的优势，发挥合作的功效，很顺利的完成了这次实践作业。首先，我们对设计的界面进行了选择，一致决定设计科学计算器的界面，便顺利的进行了GUI界面的设计。对于科学计算器功能的实习，需要加以编程。编程是一个比较复杂也相对其他部分，有一定的难度。经过学习，花费了一定的时间，最终也得到了实现。之后，对于此设计界面功能实现是否可行，我们进行了多次的检验，没有计算的问题。我们在学习和设计的过程中，总结发现，很多实际问题在对课本知识的学习当中并不能完全的发掘与体现，只有在实践中，通过自身反复的尝试操作，才能发现一些问题并很好的解决问题。也正是通过了认真的学习，才使得实践设计过程没那么多的困难，从中获益良多。更发现了MATLAB此软件功能的强大，与运用的有利之处。参考文献【1】刘卫国编《MATBLE程序设计与应用》高等教育出版社2006版【2】张圣勤编《MATABLE7.0实用教程》机械工业出版社2006版【3】刘金琨.先进PID控制与MATLAB仿真[M].北京:电子工业出版社,2003.1.TP273/L587.2【4】刘金琨.滑模变结构控制与MATLAB仿真北京清华大学出版社,2005.10.TP273/L587.2-28.附件GUI设计程序functionvarargout=untitled50(varargin)%UNTITLED50M-fileforuntitled50.fig%UNTITLED50,byitself,createsanewUNTITLED50orraisestheexisting%singleton*.%%H=UNTITLED50returnsthehandletoanewUNTITLED50orthehandleto%theexistingsingleton*.%%UNTITLED50('CALLBACK',hObject,eventData,handles,...)callsthelocal%functionnamedCALLBACKinUNTITLED50.Mwiththegiveninputarguments.%%UNTITLED50('Property','Value',...)createsanewUNTITLED50orraisesthe%existingsingleton*.Startingfromtheleft,propertyvaluepairsare%appliedtotheGUIbeforeuntitled50_OpeningFunctiongetscalled.An%unrecognizedpropertynameorinvalidvaluemakespropertyapplication%stop.Allinputsarepassedtountitled50_OpeningFcnviavarargin.%%*SeeGUIOptionsonGUIDE'sToolsmenu.Choose"GUIallowsonlyone%instancetorun(singleton)".%%Seealso:GUIDE,GUIDATA,GUIHANDLES%Copyright2002-2003TheMathWorks,Inc.%Edittheabovetexttomodifytheresponsetohelpuntitled50%LastModifiedbyGUIDEv2.501-Jun-201200:22:55%Begininitializationcode-DONOTEDITgui_Singleton=1;gui_State=struct('gui_Name',mfilename,...'gui_Singleton',gui_Singleton,...'gui_OpeningFcn',@untitled50_OpeningFcn,...'gui_OutputFcn',@untitled50_OutputFcn,...'gui_LayoutFcn',[],...'gui_Callback',[]);ifnargin&&ischar(varargin{1})gui_State.gui_Callback=str2func(varargin{1});endifnargout[varargout{1:nargout}]=gui_mainfcn(gui_State,varargin{:});elsegui_mainfcn(gui_State,varargin{:});end%Endinitializationcode-DONOTEDIT%Executesjustbeforeuntitled50ismadevisible.functionuntitled50_OpeningFcn(hObject,eventdata,handles,varargin)%Thisfunctionhasnooutputargs,seeOutputFcn.%hObjecthandletofigure%eventdatareserved-tobedefinedinafutureversionofMATLAB%handlesstructurewithhandlesanduserdata(seeGUIDATA)%varargincommandlineargumentstountitled50(seeVARARGIN)%Choosedefaultcommandlineoutputforuntitled50handles.output=hObject;%Updatehandlesstructureguidata(hObject,handles);%UIWAITmakesuntitled50waitforuserresponse(seeUIRESUME)%uiwait(handles.figu
