How do I let a user choose what variable they want to assign a value to?

조회 수: 13 (최근 30일)
I am making a program where I would like it to display a list of variable names (already created inside the program) and then let the user decide which one variable they want to assign a value to (either by typing the name of the variable or by typing in some pre-set command) and then input the value to be assigned to that variable.
(To give some background this is for a unit converter program where the user would, for instance, type "feet" and then e.g. "3" and it would return what 3 feet is in metres, inches, miles, yards etc; or they could type "metres" and then e.g. "5" and it would return this value in feed, inches etc).

I would put those variable names into a drop down list (what Mathworks calls a popup).
Then the user can select one, and in the popup callback, you can execute the proper code for that selection using a switch or if/else block.
Or perhaps less user friendly, you could use the menu() function and execute the appropriate code for whatever button number they clicked on.

There's already one requires symbolic math toolbox :
Use input() or just use inputdlg() to input a value.
