Error while evaluating UIControl Callback

function gcopt_Callback(hObject, eventdata, handles)
gen = str2num(get(handles.generator,'String'));
rate = str2num(get(handles.rating,'String'));
outage = str2num(get(handles.outage,'String'));

Data = cell(gen+1, 4);
Data(:,1) = num2cell((0:gen).');

for v = 1:gen+1
    Data(v,2) = rate * Data(v,1);
end

f = figure('Position',[440 500 461 146]);
t = uitable(f);
t.ColumnName = {'User Input','Capacity Out','Capacity Available','Probability'};
t.Data = Data;
set(t,'ColumnWidth',{120});
t.Position(3) = t.Extent(3);
t.Position(4) = t.Extent(4);

I'm having this error when I'm trying to multiply the data in the for loop.

You forgot to post the error message.

You cannot multiply cells, but only the contents:

for v = 1:gen+1
  Data{v,2} = rate * Data{v,1};   % Curly braces
end

Or:

Data(:,2) = num2cell(rate * (0:gen).');

Thank you so much. I'm new to MATLAB and really appreciate the help.

You are welcome. The handling of cell arrays is not easy at the beginning. Look in the documentation for the examples:

doc cell
docsearch cell
