get input dialog for a time value (t) using in physic problem

I have a physics excercise, which requires me to get input from user for each value to calculate the math problem. My question is how can I get a range value of double (integer etc...) throw a input dialog function , please help me with this!

Hi Tuan,

As per my understanding, you want to prompt the user to input multiple values one at a time.

This can be achieved by using a loop with the "inputdlg" function to collect each value individually and store them in an array. The "inputdlg" function in MATLAB creates a pop-up dialog box that prompts the user to input text data. You can use it inside a loop to repeatedly ask for different values. Here is a sample code to achieve the same:

n = 5; % Number of time values
t = zeros(1, n); % Preallocate array for inputs

for i = 1:n
    prompt = {sprintf('Enter time value #%d:', i)};
    dlg_title = 'Input Time';
    dims = [1 35];
    definput = {'0'}; % Default input
    answer = inputdlg(prompt, dlg_title, dims, definput);
    
    if isempty(answer) % If user clicks on cancel button
        error('User cancelled the input.');
    end
    
    t(i) = str2double(answer{1});
    
    if isnan(t(i))
        error('Invalid input. Please enter a numeric value.');
    end
end

disp('Time values entered:');
disp(t);
