Hi friends, you can see the outline of the application.I want to do this application but I am so new to matlab, how should I follow a path?

I would be very happy if you help me.

One way is to attach the data to the handles structure in your pushbutton1_Callback, the Select Data button callback.

handles.col1 = col1;
% Update handles structure
guidata(hObject, handles);

Then, in pushbutton2_Callback (the callback for the calculate button), do the computation on handles.col1.

col1 = handles.col1;
if handles.radiobutton1.Value
    output = mean(col1);
    operation = 'mean';
else
    output = std(col1);
    operation = 'std';
end
message = sprintf('The %s of the %d numbers is %f', operation, length(col1), output);
uiwait(helpdlg(message));

An even more professional way would be to put all the workbook filenames into a listbox. Place a listbox on the figure and set the tag to listbox1. Then in the openingFcn, do this

files = dir('*.xls*');
filenames = {files.name};
handles.listbox1.String = filenames;

Then the pushbutton2_Callback() would get the selected filename

selectedItem = handles.listbox1.Value;
allItems = handles.listbox1.String;
selectedFileName = allItems{selectedItem};
fullFileName = fullfile(folder, baseFileName); % Make sure you set folder to whatever it is, for example pwd.
[numbers, strings, raw] = xlsread(fullFileName)

and process it. You could repurpose the pushbutton1_Callback to be a "Specify data folder..." button where you call uigetdir().

See the FAQ for more ways of sharing data between code modules.

thank you so much, and there's one last thing I want to ask, and I want to show the two results on the axes at the same time.How can I?

[Image Analyst]

I don't understand -- what's to be plotted or displayed as an image in an axes? The mean and std are just two numbers. You can use sprintf() to show them in an edit box or static text label if you want, but not an axes control.

I want to display numbers on excel

Then to see your data on an Excel worksheet, use xlswrite() to send your data to Excel, and then launch it.

xlswrite(workbookFileName, yourData);
winopen(workbookFileName); % Launch Excel with this workbook open (Windows only).
