How to create a program that compares outputs in dictionary lexicographic

a function B=compare(s,t) that outputs "1" if s<=t in dictionary lexicographic ordering, and "0" if s>t in dictionary lexicographic ordering so that you can use it in IF statements.

Hi, try this function, it worked for me !, look how I use it in the image:

    function tlex = compare(int1,int2)

    Lex = ['a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k' 'l' 'm' 'n' 'o' 'p' 'q'...
        'r' 's' 't' 'u' 'v' 'w' 'x' 'y' 'z'];

    Lex_value=1:length(Lex);

    a=find(Lex == int1); 
    b=find(Lex == int2); 

    if Lex_value(a) > Lex_value(b)
        tlex=0;
    elseif Lex_value(a)<= Lex_value(b)
        tlex=1;
    end

    end
