create menu with input
显示 更早的评论
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,
~

this seems to work in R2016b
x=5;
xx=num2str([1:x]');
yy=mat2cell(xx,ones(x,1),1);
menu('choose',yy(:))

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.

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)
