Assign values to a string in Matlab

For example I have:

X ='abcaaabc';

How can I get it like

Y= [a b c a a a b c];

and

Y1= [0 1 2 0 0 0 1 2]

Answer 1

Y1=X-97

You can't have the Y you want. Maybe Y=[X(:)], or Y=transpose(string(X'))

>> X = 'abcaaabc';
>> Y = num2cell(X)
Y = 
    'a'    'b'    'c'    'a'    'a'    'a'    'b'    'c'
>> Y1 = X-97
Y1 =
     0     1     2     0     0     0     1     2
