How do I print a 6x6 output matrix on app designer table ?

Hello All

How can I use the table field in app designer to print my 6x6 output matrix on the App interface?

I also needed to have header names of my choice and not Column1 ,etc but also index in string form. is that possible ?

See the attached app. You can set the column name in the component browser pane on the right of the app designer window.

Thank you , but I forgot to mention the version 2017b. shall you please change it ?

[Ameer Hamza]

Sure. Please check the attached file.

[farzad]

Thank you so much! there is only one problem when you attach these files, they open only once in app designer and the next time , there is an unknown error that stops matlab from opening them

[Ameer Hamza]

I am not sure. It might be caused by exporting the file from R2020a to R2017b. There might be some issues with compatibility.

shall you kindly write the lines here ? for both of the buttons ?

there was a num2cell ? please just write them here . thank you so much

These two images show the settings of settings and code in app designer. There are two functions: one is the startup Fcn for the figure and the other is push button callback.

Code is also pasted here:

methods (Access = private)

    % Code that executes after component creation
    function startupFcn(app)
        app.UITable.Data = num2cell(zeros(5));
    end

    % Button pushed function: ShowRandomMatrixButton
    function ShowRandomMatrixButtonPushed(app, event)
        app.UITable.Data = num2cell(rand(5));
    end
end

thank you , but how do you create the startup fcn for table ?

I can only create one of these functions :

% Cell edit callback: UITable
        function UITableCellEdit(app, event)
            
        end

or this one

        % Cell selection callback: UITable
        function UITableCellSelection(app, event)
            
        end
    end

[Ameer Hamza]

No, you don't need to create startup function for table. That is the startup function of the figure. Right-Click on an empty location canvas and in the callback menu select the figure startuo callback.
