I agree with all of your statements especially the one about entropy. I will submit version 2 shortly. Thank you

The length of the password and the number of digits, upper and lowercase letters must be specified. Special characters as !"ยง$%&/()=?*+~#-:;,.-<>|'@^ and space are not possible. This is not a typical strategy to create a password, because this reduces the entropy substantially. A simpler and more efficient approach to get a random password of n characters:
v = char([33:95, 97:27]);
p = v(ceil(rand(1,n)*length(v)));
But it is impossible to remember such passwords and it is very likely that you find them written down under the keyboard.
I prefer passwords like "65eels!NoHeels" or "I sit right beside the 5TH prime".
However, the function works, has a very lean help text, but no H1 line (see LOOKFOR). It would be more efficient to use 'ABC...' instead of ['A', 'B', 'C', ...] and to shuffle the characters of the string instead of creating an index vector at first, shuffle the index and apply it to the string finally.
The unnecessary weakness of the password is the main reason for my low voting.
