How to "Pretty( )" output in GUI?

Hello all, I am working on my assignment and I have created a GUI in Matlab one part of which takes user input (tag:inputfun) and integrates it and its working perfectly but I want that output to be as we write on paper i.e. in the form of "Pretty( )" so that user can easily understand. I tried a lot but I was unable to do that. Can anyone please help me so that I can submit my assignment as soon as possible. Hoping for Answer :)

Answer 1

[Walter Roberson]

outstr = evalc(pretty(c));

Remember to make handles.answers something that is fixed-width font (not proportional.) If it is a uicontrol 'text' or 'edit' box, make sure that its Max property is set to at least 2.

You might also need to use

outstrcell = regexp( outstr, '\n', 'split' );

and use that as your String

Sir but why this

b=get(handles.inputfun,'string');
c=int(sym(b));
set(handles.answer,'string',pretty(c))

doesn't makes output to be in the form of

Pretty(----)

why I get this error

Error using sym.pretty
Too many output arguments.

Error in derivator>btndiff_Callback (line 130)
set(handles.answer,'string',pretty(c))

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in derivator (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)derivator('btndiff_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

Please help if its possible.

Try

outstr = evalc('pretty(c)');

[Albert Shesman]

like this Sir?

b=get(handles.inputfun,'string');
c=int(sym(b));
set(handles.answer,'string',char(c))

outstr = evalc('pretty(c)');

[Walter Roberson]

b=get(handles.inputfun,'string');
c=int(sym(b));
outstr = evalc('pretty(c)');
set(handles.answer,'string',outstr)

I never heard of Petty(), but you can click anywhere in the editor window and type control-a followed by control-i to fix the indenting. If you highlight a section of code, it will fix up that highlighted section only.

[Image Analyst]

I don't know what you consider the "output" to be, but if it's not your code and it's some measurements that you want to write to a file, you can use fprintf() to make it look just like you want it.

[Albert Shesman]

Sir its not "Petty()" its "Pretty()" I have Matlab R2013a Version, may be there's some difference because we're using different versions.

[Image Analyst]

Sorry, I knew that - just a typo. Anyway, I don't have it so it must be in a toolbox that you have (and should list above in the Products section) that I don't have.

[Albert Shesman]

oh yes am sorry for that, it's related to 'symbolic mathtoolbox'

[Image Analyst]

You still didn't list it in the Products section, so I did it for you.

[Albert Shesman]

oops sorry :p.. and thaaannkuu to you tooo thanku sir :)
