This video shows the steps to create a simple casino type game in MATLAB using App designer. GUI is created using App Gauge and Spinner and labels to mark the winning terms.

Towards the end of this video it shows how to package the App Designer code in an application package (installer) or matlab app which can be shared with friends or colleagues.

How to use table in matlab app (GUI) to enter value and execute and show result in figure or in another table. It means one table to enter initial values and another table to show result

I don’t think there is in-built table provided in App Designer. What you can do is insert series of Text Area or Edit Boxes in your Design. And in the value change callback write your code to read and display the values in the respective object of the figure.
