MATLAB: Undefined operator ‘<=' for input arguments of type 'struct'.

Question

I want to retrieve data from the table and I will make an if else statement. Please help me

matriks_fitur = arrayfun(@num2str, handles.matriks_fitur, 'un', 0);
a = (strcmp(matriks_fitur, 'fitur_spasi'));
b= get(handles.TableFitur);
if b <=18 
    hasil = 'Extrovert';
elseif b == 42.5000 
    hasil = 'Introvert';
else
    hasil = 'Empaty';
end
set(handles.targetkelas,'String',[num2str(hasil)]);

I get an error message as follows

Undefined operator '<=' for input arguments of type 'struct'.

Error in pelatihan_data>Target_Callback (line 1897)

if b <=18

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in pelatihan_data (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)pelatihan_data('Target_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

if anyone has any suggestions and can help me then i am very grateful

Answer 1

It would appear that

b= get(handles.TableFitur);

has set b to a structure variable, whereas you expected it to be a scalar number.
