Hello,

I have a few variables that I would like to add into columns of a Table in MatLab App designer.

Ma variables are: app.A, app.B, app.C

I set the Table (called app.Table) to have 3 columns from the design view, but I can't figure out how to add my variables to it.

This is what I have to far:

app.Table{1}=(app.A); %gives me error 'Unable to perform assignment because brace indexing is not supported for variables of this type.'
app.Table{2}=(app.B);
app.Table{3}=(app.C);

Can anyone help please ?

Have you tried row and column indexing?

I am not sure how ? The variables A, B and C are all 1x50. Please elaborate if possible.

Thank you everyone for your help. This is how I solved my problem:

properties (Access = public)
    t;
    A;
    B;
    C;
    
% Button pushed function: RunButton
        function RunButtonPushed(app, event)
                 %generate table           
                 app.t = [A' B' C']; %create matrix of table data
                 app.Table.Data = app.t; % Add data to the Table UI Component
        end
 % Cell edit callback: Table
        function TableCellEdit(app, event)
            app.Table=app.table(A,B,C,'VariableNames',{'A' 'B' 'C'});
        end

There are probably a couple things wrong with

app.Table{1}=(app.A)

First, if app.Table doesn't yet exist, you are not creating a table. Second, even if app.Table exists, you need to use two subscripts on a table.

I imagine you want something like

app.Table = table(app.A,app.B,app.C,'VariableNames',{'A' 'B' 'C'});

Hi,

Thank you for responding. I have defined this for the table:

% Cell edit callback: Table
        function TableCellEdit(app, event)
            app.Table=app.table(app.A,app.B,app.C,'VariableNames',{'A' 'B' 'C'});
        end
