Save data in excel sheet using pushbutton.

i am using below code at the click of pushbutton. i want to create an excel sheet. which has 2 colums(Frames(1x1 double) & Diameter(1x1 double)) and multiple rows. for this code it will write only 1 row.

% --- Executes on button press in SaveTag.
function SaveTag_Callback(hObject, eventdata, handles)
% hObject    handle to SaveTag (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% global Whole_Data
Whole_Data = {'Frames','Diameter'};
framecount=getappdata(handles.UFramesTag,'original');
dia=getappdata(handles.CalculateTag,'Diam');
Data = {framecount, num2str(dia)};
Whole_Dataa = vertcat(Whole_Data, Data);
xlswrite('Diameters.xlsx', Whole_Dataa);

but this is thowing an error. and i dont know what dimensions i have to change to make it work. Error screenshot is below.

The problem is either with framecount or dia. We have no idea what size they are nor what their type is. It's also unclear why you convert dia into a string. Why not write the number directly in excel?

You would probably find it much easier to use modern matlab tools such as writetable instead of xlsread. Your code may be equivalent (no guarantee since as said, we don't know anything about framecount and dia):

framecount=getappdata(handles.UFramesTag,'original');
dia=getappdata(handles.CalculateTag,'Diam');
WholeData = table(framecount, dia, 'VariableNames', {'Frames', 'Diameter'});
writetable(WholeData, 'Diameters.xlsx');

framecount has count of each frame. in this code it has frame no 02, dia has a diameter against this frame.i cant tell you about their types. because i dont know how to check their types.,As my workspace is not showing any details getappdata variables.

Secondly, converting dia into string is not necessary, iwas just doing hit and trial to resolve error.Otherwise without converting to string also doesnot create any positive change to error.

Lastly, i have used your above mentioned code(mentioned below). but its still not working and throwing below error.

Please help me with this error.

% --- Executes on button press in SaveTag.
function SaveTag_Callback(hObject, eventdata, handles)
framecount=getappdata(handles.UFramesTag,'original');
dia=getappdata(handles.CalculateTag,'Diam');
% Data = {framecount, dia};
% Whole_Dataa = vertcat(Whole_Data, Data);
% xlswrite('Diameters.xlsx', Whole_Dataa);
%  winopen('Diameters.xlsx');

WholeData = table(framecount, dia, true, {'Frames', 'Diameter'});
writetable(WholeData, 'Diameters.xlsx');
