Hi,
I want to enter a vector 1x18 into edit text in GUI, e.g:
0.03 0.02 0.01 0.02 0.01 0.01 0.02 0.01 0.04 0.03 0.02 0.01 0.01 0.02 0.02 0.01 0.01 0.1
So far I used to enter only single value. My current callback:
function edit40_Callback(hObject, eventdata, handles)
% hObject handle to edit40 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of edit40 as text
% str2double(get(hObject,'String')) returns contents of edit40 as a double
InString = get(hObject, 'String');
InString = strrep(InString, ',', '.');
eta_tot=str2double(InString);
set(handles.edit40, 'String', InString);
if isnan(eta_tot)
errordlg('You must enter a numeric value','Invalid Input','modal')
uicontrol(hObject)
return
else
end
if (eta_tot<0 | eta_tot>1)
errordlg('Value should range from 0 to 1','Invalid Input','modal')
uicontrol(hObject)
end
Thanks for any ideas,
Dominika

A few places to look:
help strread
help str2num
help textscan
There are many ways to do what your looking for.

Thank you for your suggestions. I try with str2double:
function edit40_Callback(hObject, eventdata, handles)
% hObject handle to edit40 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of edit40 as text
% str2double(get(hObject,'String')) returns contents of edit40 as a double
InString = get(hObject, 'String');
display(InString)
eta_tot=str2double('InString');
celldisp(eta_tot)
I get an error while trying to display eta_tot:
InString =
'0.1 0.1'
Error using celldisp (line 15)
Must be a cell array.
Error in PROGRAM>edit40_Callback (line 1546)
celldisp(eta_tot)

debug your code to find out whats going wrong - you will learn more doing that that me highlighting the errors.
Try simple examples at the matlab commandline to understand how functions work.
