MATLAB: Encryption scheme operands

alphabetdecryption

I'm wondering if anyone understands how to write a code such that each letter of the alphabet is given a corresponding number from 1-26, and 27 is a blank space… Basically, I have to decipher a matrix. I tried using something like this;
Alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
numbers = [1,12,7,5,2;18,1,27,27,27]
letters = Alphabet(numbers)
The output should be ALGEBRA, but I get an error message.

You forgot a space in your definition:
Alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ ';
numbers = [1,12,7,5,2;18,1,27,27,27];
letters = Alphabet(numbers)
