Hi, I created a table in app designer, this table contains 5 columns (description,mass, x, y, z), i want to display a result (position center of gravity) in a numeric edit field, but i don't know how to manipulate the data from the table to do my calculations. I want to use the second, third, fourth e fifth columns and each row to do my calculus, but i dont't know how to do that in appDesigner.

Thank you!

Marco

Your callback doesn't like your brackets.

%%%% I'm mimicking your table
fig = uifigure;
t = uitable(fig,'ColumnEditable',true,...
'ColumnName',{'description','mass','x','y','z'},...
'Data',rand(5,5));
%%%% The only thing different is that you need to change the brackets, name
%%%% of your table (mine is t, yours is obviously app.UITable), and add
%%%% another . in your x_cog calculation.
mass_vector = t.Data(:,2);
x_vector = t.Data(:,3);
x_cog = sum(mass_vector.*x_vector)./sum(mass_vector);
app.NumericEditField.Value = x_cog;
