Hi, im new in matlab, these are my codes,

%Kosongkan Tampilan
set(handles.InputA,'string','');
set(handles.InputB,'string','');
set(handles.InputC,'string','');
set(handles.InputD,'string','');
set(handles.InputE,'string','');
set(handles.InputF,'string','');
set(handles.Inputx1,'string','');
set(handles.Inputx2,'string','');
set(handles.x1final,'string','');
set(handles.x2final,'string','');
set(handles.InputTeliti,'string','');
%Ambil Data
A=str2double(get(handles.InputA,'string'));
B=str2double(get(handles.InputB,'string'));
C=str2double(get(handles.InputC,'string'));
D=str2double(get(handles.InputD,'string'));
E=str2double(get(handles.InputE,'string'));
F=str2double(get(handles.InputF,'string'));
x01=str2double(get(handles.Inputx1,'string'));
x02=str2double(get(handles.Inputx2,'string'));
T=str2num(get(handles.InputTeliti,'string'));
%Inisialisasi Variabel
syms  x x1 x2 L FL
%Program Utama
x=[x01 x02];
FX=A*x1^2+B*x2^2+C*x1*x2+D*x1+E*x2+F;
VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E];
norm=sqrt(VF(1)^2+VF(2)^2);
d=VF*-1;
xn=[x(1)+L*d(1);x(2)+L*d(2)];
FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F;
Lamda=solve(diff(FL,L),0);
xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)];
%Mengisi Tabel
set(handles.Tabel1,'data',num2cell(x(1)));
guidata(hObject, handles);
while double(norm) > double(T)
    x=xn
    VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E];
    norm=sqrt(VF(1)^2+VF(2)^2);
    d=VF*-1;
    xn=[x(1)+L*d(1);x(2)+L*d(2)];
    FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F;
    Lamda=solve(diff(FL,L)==0,L);
    xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)];
    Data=[norm xn(1) xn(2) Lamda];
    set(handles.Tabel,'string',Data);
    guidata(hObject, handles);
end

it's a steepest descent code, and when I pushed the push button, it said: Reference to non-existent field 'Tabel1'.

Error in SDNyoman>MULAI_Callback (line 144)
set(handles.Tabel1,'data',num2cell(x(1)));
Error in gui_mainfcn (line 96)
        feval(varargin{:});
Error in SDNyoman (line 42)
    gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)SDNyoman('MULAI_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback

Thank you.

Are you sure you didn't misspell it? Are you sure it's not Table1 instead of Tabel1?

It works, now I have a problem for insert data to table. Code:

{ %Kosongkan Tampilan set(handles.InputA,'string',''); set(handles.InputB,'string',''); set(handles.InputC,'string',''); set(handles.InputD,'string',''); set(handles.InputE,'string',''); set(handles.InputF,'string',''); set(handles.Inputx1,'string',''); set(handles.Inputx2,'string',''); set(handles.x1final,'string',''); set(handles.x2final,'string',''); set(handles.InputTeliti,'string','');

%Ambil Data A=str2double(get(handles.InputA,'string')); B=str2double(get(handles.InputB,'string')); C=str2double(get(handles.InputC,'string')); D=str2double(get(handles.InputD,'string')); E=str2double(get(handles.InputE,'string')); F=str2double(get(handles.InputF,'string')); x01=str2double(get(handles.Inputx1,'string')); x02=str2double(get(handles.Inputx2,'string')); T=str2num(get(handles.InputTeliti,'string'));

%Inisialisasi Variabel syms x x1 x2 L FL

%Program Utama

x=[x01 x02]; VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E]; norm=sqrt(VF(1)^2+VF(2)^2); d=VF*-1; xn=[x(1)+L*d(1);x(2)+L*d(2)]; FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F; Lamda=solve(diff(FL,L),0); xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)];

hasil=[norm x(1) x(2) Lamda]; set(handles.Tabel1,'data',hasil); guidata(hObject, handles); while double(norm) > double(T) x=xn VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E]; norm=sqrt(VF(1)^2+VF(2)^2); d=VF*-1; xn=[x(1)+L*d(1);x(2)+L*d(2)]; FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F; Lamda=solve(diff(FL,L),0); xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)]; end

The command window said: Error using set Data must be a numeric, logical, or cell array

Error in SDNyoman>MULAI_Callback (line 145) set(handles.Tabel1,'data',hasil);

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in SDNyoman (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)SDNyoman('MULAI_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback }

does my data is a double?

I don't know - I don't have that toolbox. Did you try this:

hasil = double(hasil);

If that doesn't work, then I don't know. I added the Symbolic Math Toolbox to the products tag. You should do this when you make up the question initially.
