If I have a 20-digit numeric string, how can I convert it to an array where the elements are the digits of the string?

For example, if I have a string, such as

n='9555688756196283262165034064'

how can I convert it to the vector

b=[9 5 5 5 6 8 8 7 5 6 1 9 6 2 8 3 2 6 2 1 6 5 0 3 4 0 6 4]?

I tried using the following code, but Matlab is not accurate, and the imprecisions throw off the rest of my script:

n='9555688756196283262165034064';
a=str2double(n);
b=num2str(a) - '0';

This is not generally recommended, but it works here:

n = '9555688756196283262165034064';
b = n - '0'

b =

    Columns 1 through 16

       9     5     5     5     6     8     8     7     5     6     1     9     6     2     8     3

    Columns 17 through 28

       2     6     2     1     6     5     0     3     4     0     6     4

Ok, try this code:

n = '9555688756196283262165034064';
matrix = arrayfun(@str2double ,n);
