Splitting a sentence into an array of letters

I'm new to MATLAB. I would like to learn how to convert or split a string (maybe a sentence or a passange) to an array of letters. For example:
I have a string of 'I am happy'
I want my end result of my array to be [ 'I' ' ' 'a' 'm' ' ' 'h' 'a' 'p' 'p' 'y' '.']
How can I do that? Thank you for all your advice and help.

Because square brackets are a concatenation operator, your two examples are equivalent (apart from the dot at the end, which appears out of nowhere):
A = 'I am happy' % I have a string of
B = [ 'I' ' ' 'a' 'm' ' ' 'h' 'a' 'p' 'p' 'y' '.'] % I want my end result of my array to be

str = 'I am happy' % characar array
% the char array str is stored as [ 'I' ' ' 'a' 'm' ' ' 'h' 'a' 'p' 'p' 'y'
% '.'] internaly. It only display as 'I am happy' for compactness.
%
% You can get the individual character
str(3)
% if you transpose str, it is a column vector of characters
str'
