HI. I'm designing a gui.
I'm using r2018a and guide.
I want to input a string, which is a person's name, into a edit1 box, and then display that string on the edit2 box.
And I finally want to load .mat file named the string that I entered in edit1 box.
I can input a string and display, but I got error message on load.
Error code said, ' load should be string arrays or character arrays.'
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
user_name = get(handles.edit1, 'String');
set(handles.edit2, 'String', user_name)
user_data = load(user_name); %user_name is string type, right? what's the problem?
plot(handles.axis1, user_data)
Plz give me some advice. Appreciate in advance ;)

I've found that sometimes with code like
user_name = get(handles.edit1, 'String');
user_name is a cell array (with one string element) and so is not a character array. What you may have to do here is to convert this into a string with char as
user_data = load(char(user_name));

Wow amazing Thanks I solved problem
user_data = load(char(user_name));
or
user_data = load(string(user_name));
It works well.
I'm a begginer so I always miss that kind of small detail.
Thank you for your advice
