converting string code into numbers?

Write a function m-file called stringcode that takes a string as input and produces an array containing a code for each letter in the string with A = 0, B = 1, ..., Z = 25 and all other characters getting the value 26
Hints
- Convert the string to all upper case (using the command upper).
- Convert the string to an array of ascii codes (use double).
- Loop through the array and change the codes to the right values. Look up the codes for ’A’ and ’Z’.
here is my code
function num = stringcode( word )
asc = double(upper(word))
if asc >= 33 & asc <=47 & asc < 0
asc = 26
else asc = double(upper(word))
end
% simple arithmetic
num = asc - double('A')
end
I cant get the special characters to come up as the number 26

Also, you need to use a single pipe character for an array, so that second line doesn't work.
