Matlab's menu() function

Let me tell you about this fascinating little function in Matlab called menu(). It's a nifty tool that allows you to make your scripts interactive with the user.

menu(text, options)

The function has two or more parameters:

• The first parameter is the text to be displayed to the user.
• The second parameter is the list of options to choose from, separated by a comma.

It's a very useful function because it makes the script interactive with the user.

How does it work? The way it works is when Matlab encounters the function, it pauses the script's execution and pops up a window on the screen displaying a message and a list of options. The user can then make their selection by clicking on one of the choices. Matlab then stores the user's selection in a variable and continues executing the script. It's quite simple and yet very useful.

Let me show you an example.

You can use the menu() function to display two options - "even" and "odd" - for the user to choose from.

x = menu("even or odd", "even", "odd");
disp(x);

The script would then assign the value of 1 to the variable x if the user selects "even", or 2 if the user selects "odd".

You can then use this variable to make the script behave differently depending on the user's choice.

Note. One thing to keep in mind is that the menu() function also allows for the possibility that the user may close the window without making a selection. In this case, the script assigns the value 0 to the variable x.

This way you can make the script interact with the user using Matlab's graphical interface.

Overall, the menu() function is a powerful tool that can greatly enhance the interactivity of your Matlab scripts. It's definitely worth giving a try!
