How can I get a prompt to repeat for a user given input?

Hello!

I'm pretty new to MATLAB, and I was wondering how to write a code that would repeat a prompt and save each answer to a new variable.

For example, I want the user to answer the question 'How many states are you going to?' using the prompt:

    states = inputdlg('How many states are you going to?');
       states = str2num(states{:});

I then want the question 'How many days are you spending in state 1?' to come up using:

    days(1)= inputdlg('How many days are you spending in state (1)?');

Which would repeat for state 1: states. Im using the answer from the number of days per state further along in the code to later get a total amount of money spent, which I can figure out. I'm just a little stuck here.

Thanks!

Hi, Liz. I think you should use sprintf.

states = inputdlg('How many states are you going to?');
states = str2num(states{:}); 
for i = 1 : states
st = sprintf('How many days are you spending in state %d?', i);
days(i) = inputdlg(st)
end

For example, I put my states as 3 and days as 1, 2 and 4.

days = 

    '1'    '2'    '4'

To access the element,

days(1)

ans =

    '1'

Hope it helps.
