create menu with input

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,

~

Thanks for your answer,

but unfortunately I got the following error

Undefined function 'string' for input arguments of type 'double'.

I am using MATLAB version 2016a

Thanks,

[Fangjun Jiang]

this seems to work in R2016b

x=5;
xx=num2str([1:x]');
yy=mat2cell(xx,ones(x,1),1);
menu('choose',yy(:))

Thanks again for your prompt relpy.

It's working now, I just have one more question, I would like to have specfic data for each selection in the menu but not working, could you help me

So I would like my have an output for each selection from the menu , is it possible,

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

[Fangjun Jiang]

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)
