Error while evaluating uicontrol Callback

2 views (last 30 days)
I created pushbutton in GUI;
% --- Executes on button press in pushbutton1.
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)
[FileName1,PathName] = uigetfile('*.xlsx','Select the excel file');
[num,txt1,raw] = xlsread(FileName1);
%when user click pushbutton then click close the "select the excel file" window following errors occur;
Error using xlsread
Filename must be a string.
Error in helmert_fig>pushbutton1_Callback (line 84)
[num,txt1,raw] = xlsread(FileName1);
Error in gui_mainfcn (line 96)
Error in helmert_fig (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)helmert_fig('pushbutton1_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
%how I can modify the xlsread function to supress these errors when user close the window without select any file to read?

if FileName1 ~= 0
[num,txt1,raw] = xlsread(FileName1);
Obviously you will have to also include any further code that uses those created variables inside the if statement also.
