Hi,

I have a function which requires some parameters. Now, I want to make a user interface, so the user does not have to change the parameters by changing the code but has just to fill in some field and press start or something. Can somebody give me an idea on how to do that in matlab? I didn't have to do anything with GUI's or user interfaces before so i don't really know where to start.

"I understand, but then you'd still have to use the Matlab code to change the parameters. I want to make this userface because my function is supposed to be used by people who don't know matlab at all."

Do you mean you want people who don't even have access to Matlab to be able to use it as an executable or just that people shouldn't need to have to write Matlab statements to use it?

If you want to build a standalone executable you would need the Matlab Compiler toolbox. Doesn't make a difference to the GUI you would build except that if your only reason to build one was for external users and you don't have the Compiler toolbox it may change your decision on if it is needed or not.

Contrary to popular opinion, i find MATLAB GUIde very useful to provide a GUI for my scripts/functions.

try

guide

or

appdesigner

You can either use the tools GUIDE or APPDesigner, or create the GUI programatically. It matters if you want to learn something about the creation of GUIs or need a fast and cheap solution only.

This would be a way to start for a programatical solution:

function yourGUI  % Use a better name, of course
DlgH = figure( ...
  'Name',          'YourGUI', ...
  'IntegerHandle', 'off', ...
  'WindowStyle',   'normal', ...
  'MenuBar',       'none', ...
  'NumberTitle',   'off', ...
  'Resize',        'off', ...
  'Units',         'pixels', ...
  'Position',      [100, 100, 400, 300], ...
  'NextPlot',      'add');
uicontrol('Style', 'PushButton', 'String', 'Run function', ...
  'Position', [10, 10, 380, 25], ...
  'Callback'  @RunFunction);
UIData = guidata(ButtonH););
UIData.Param1 = uicontrol('Style', 'edit', 'String', '', ...
  'Position', [10, 360, 300, 25]);
UIData.FileSelect = uicontrol('Style', 'PushButton', ...
  'String', '...', 'Callback', @FileSelect, ...
  'Position', [320, 360, 80, 25]);
UIData.Param2 = uicontrol('Style', 'edit', 'String', '', ...
  'Position', [10, 360, 300, 25], ...
  'Callback', @CheckValue);
guidata(FlgH, UIData);
end
function FileSelect(ButtonH, EventData)
UIData = guidata(ButtonH);
[FileName, FilePath] = uigetfile('*.xlsx', 'Select an Excel file');
if ischar(FileName);
  File = fullfile(FilePath, FileName);
  set(UIData.Param1, 'String', File);
end
end
function CheckValue(EditH, EventData)
Str = get(EditH, 'String');
Num = sscanf(Str, '%g', 1);
if isempty(Num)
  set(EditH, 'String', 'Enter a number!', ...
      'ForeGroundColor', [1,0,0], ...
      'UserData', []);    % Invalid
else
  set(EditH, 'String', sprintf('%g', Num), ...
      'ForeGroundColor', [0,0,0], ...
      'UserData', true);  % Valid number
end
end
function RunFunction(ButtonH, EventData)
UIData = guidata(ButtonH);
if isempty(get(UIData.Param2, 'UserData'))
  set(UIData.Param2, 'BackGroundColor', [1,0,0]);
  pause(0.5);
  set(UIData.Param2, 'BackGroundColor', [1,1,1]);
  return;
end
File   = get(UIData.Param1);
Value  = sscanf(get(UIData.Param2, 'String'), '%g', 1);
% Now run your function:
yourFunction(File, Value);
end

UNTESTED CODE! This was written in the forum's interface only. Please debug this by your own. I assume the layout is cruel, but you can adjust the 'Position' properties manually.

Hi thank you very much! Although I'd like to learn something about programming a GUI on myself, I don't have that much time for this task, so I think I might use the tools.

Or, just use the builtin widgets interface to get the parameters may be enough...

fn=uigetfile('*.xls','Select Input File');
data=xlsread(fn);        
P1=str2num(inputdlg('Enter Parameter 1')); 
P2=str2num(inputdlg('Enter Parameter 2')); 
output = yourfunction(data,[P1,P2]);
