Display "hello world" in GUI's app.systemlog

I have a blank MATLAB application, I dragged in the System Log (called "app.systemlog"). I have also dragged in a button which runs a script called "test.m"

How do I display "hello world" in my GUIs System Log by running "test.m" ? Please specify what I would need to adjust in both the "test.m" and in the application itself.

Any help is greatly appreciated!

Hi @Kyle,

I assume that the reference to SystemLog pertains to the following UI component:

https://www.mathworks.com/help/slrealtime/api/slrealtime.ui.control.systemlog.html

According to the documentation, this component is intended for displaying console log messages from a real-time Speedgoat target computer within a MATLAB app or UI.

However, for the described use case— displaying custom messages such as "hello world"— the TextArea UI component may be more appropriate. This component allows for programmatic updates to its content, making it suitable for general-purpose logging within an app. Further details on the TextArea component are available here:

https://www.mathworks.com/help/matlab/ref/matlab.ui.control.textarea.html

To implement the desired functionality, the test.m script can be modified as follows:

function test(app)
    app.TextArea.Value = [app.TextArea.Value; "hello world"];
end

This code appends the string "hello world" to the existing content of the TextArea.

Hope this helps !
