Error using plot Conversion to double from cell is not possible.

I don't why this isn't working.

I get an error on

 a = plot (x1,y1);

which is at the end of my code.

     function calc_Callback(hObject, eventdata, handles)
    % hObject    handle to calc (see GCBO)
    % eventdata  reserved - to be defined in a future version of MATLAB
    % handles    structure with handles and user data (see GUIDATA)
    % blah = get(handles.calc, 'string');
    set(handles.x2, 'string', 'hi');
    XX1 = get(handles.x1, 'string');
    YY1 = get(handles.y1, 'string');
    RR1 = get(handles.r1, 'string');

XX2 = get(handles.x2, 'string');
YY2 = get(handles.y2, 'string');
RR2 = get(handles.r2, 'string');

XX3 = get(handles.x3, 'string');
YY3 = get(handles.y3, 'string');
RR3 = get(handles.r3, 'string');

% x1 = X1{1}; %getting the contents of each var
x1 = XX1;
y1 = YY1{1};
r1 = RR1{1};
%x2 = X2{1};
x2 = XX2;
y2 = YY2{1};
r2 = RR2{1};
x3 = XX3{1};
y3 = YY3{1};
r3 = RR3{1};

min = r1;

disp(['r1 ' num2str(min)]);
disp(['r2 ' num2str(r2)]);
if(min > r2)
    min = r2;
end
if (min > r3)
    min = r3;
end

temp = min;
min = temp/10;

disp(x1);
hold on
a = plot (x1,y1);
%b=plot(X2,Y2);

In debug mode, do

 K>> whos x1 y1

right before the last line and show us the output.

Answer 1

[Andrew Reibold]

You are trying to plot a 'cell'. I believe the plot command only works for doubles.

Convert the cell to a double first.

Answer 2

[David (degtusmc)]

As Andrew mentioned above, I believe is because you are trying to plot a cell. If you want to convert from cell to double you could do the following:

cell2mat -> mat2str -> str2num %type help followed by the function if in doubt

I know this is probably not the most efficient way, but you should be able to figure it out with one of the conversions. Hope this helps.
