Hey all,
I have been trying to create menu with input command, I wanna the menu displays choices as buttons in a dialog box depends on how many element number I added
For example I wanna my output to be as the following
x=input('enter elments number' :) % which as an example =3
then
output = menu('Choose a element number','1 ','2 ','3')
I wanna do it automatically so if x=input('enter elments number' :) % which as an example =4
output = menu('Choose a element number','1 ','2 ','3','4')
Can anyone help ?
Thanks,
~

menu() returns the index number so you konw which button the user clicked. To get different data based on this input, you need to do it afterwards in your program.

I think you misunderstood me, because I would like to add (for loop , or while )to add for each index a command then store them ?
Like the following
x=5;
xx=num2str([1:x]');
yy=mat2cell(xx,ones(x,1),1);
menu('choose',yy(:))
for menu(1)
f=2
menu(2)
f=3 and so on...
Hope you get what I want

What is "for menu(1)", "menu(2)"? There is no such syntax. I could only guess this is what you want.
f=[10, 200, 3000];
selection=menu('choose','1','2','3');
output=f(selection)
