Function 'subsindex' is not defined for values of class 'cell'

TIP1 = {'ITS A GREAT CAR'};

setappdata(0,'TIP1',TIP1);

TIP2 = {'ITS A USUAL CAR'};

setappdata(0,'TIP2',TIP2);

function popupmenu1_Callback(hObject, eventdata, handles)

TIP1 = getappdata(0,'TIP1');

TIP2 = getappdata(0,'TIP2');

selectedCar = handles.popupmenu1.Value;

switch selectedCar

case 2

owners = TIP1;

case 3

owners = TIP2;

end

str = [];

for k = 1 : length(owners)

str = fprintf('%s\n%s', str, owners{k});

end

handles.edit1.Max = 2;

handles.edit1.String = owners;

function pushbutton2_Callback(hObject, eventdata, handles)

TIP1 = getappdata(0,'TIP1');

intraretext = handles.popupmenu1.String;

TIP1 = [handles.edit1.String(TIP1);intraretext];

setappdata(0,'TIP1',TIP1);

when I push button 1 receive this error

Error using subsindex

what's wrong?Thanks!

What's wrong is that TIP1 is a cell array, and you can't use a cell array as an index, as in here you are attempting to access the TIP1 index of handles.edit1.String:

handles.edit1.String(TIP1)

(What the right thing would be is hard to say because I don't know what the intent is.)

The intention is to modify that TIP1 every time a I push button 1 with another text from text box. So the new value of TIP1 to be modified. Thank you

[Voss]

This will prepend edit1's String to the beginning of TIP1 and store the result as TIP1, assuming both are cell arrays or string arrays:

TIP1 = [handles.edit1.String(:); TIP1(:)];

Maybe that's similar to what you're trying to do, and you can modify it as necessary.

What is the purpose of

handles.edit1.String(TIP1)

Here TIP1 = {'ITS A GREAT CAR'} is used as index of the variable replied by handles.edit1.String . I cannot guess reliably, what you want to achieve with this code.

Storing values in the ApplicationData of the root object suffers from the same drawbacks as global variables. Avoid this to improve the quality of the code.
