Using randi instead of floor and rand.

This is my password generator.

% Password Generator

% 1. Input Parameters
uppercase = 'A':'Z';
lowercase = 'a':'z';
numbers   = '0':'9';
letters   = [uppercase, lowercase];
characters= [letters, numbers];

% 2. Ouputput Password
passwd_length = input('enter the length');
passwd(1) = letters(randi(numel(letters)));
passwd(2:passwd_length) = characters ( 1 + floor(rand(1, passwd_length - 1) .* numel(characters)) )

In the last line I have used the floor command with rand. Is there a way where I can use randi instead.

This is how I’d do it:

passwd(2:passwd_length) = characters (randi(length(characters ), 1, (passwd_length-1)))
