Assigning letters to numbers

Hi, I have a simple question. I'm trying to do a Hill Cipher decryption as a project, and I wanted to add "space" as 0, and start A as 1, all the way through Z as 26, so that the cipher will be done with mod27 instead. I could get my alphabets

alphabets = 'A':'Z';

Map(alphabets) = 1:length(alphabets);

But I would like to start from "space" as 0.

alphabets = [' ', 'A':'Z'];
Map(alphabets) = 0:numel(alphabets)-1;
