I want to make an array with one character, and i want the user to be able to write how many. For example:
cha='hello';
cha=upper(cha);
length=length(cha);
now, lets say i want to create an array with only dots and i want it to be as many as 'length' is (in this case 5, so i want this to be shown: ..... ). How do I proceed?
thanks

Here's one way:
L = length(cha);
A = repmat('.',[1 L])
Also, I recommend against defining a variable named "length", because it is a MATLAB command. That often leads to confusion down the road.

Easy
char(46*ones(size(cha)))
Not so easy
regexprep(char,'\w','.')
:)
