I want to convert a string containing letters to a double in matlab-CodePudding

East_Seed_1="MIA";
East_Seed_8="ATL";

for i=1:7
    s=rand;

    if s<MIA_prob_vs_ATL
        s=1;

I want to create an algorithm that, given probabilities of each team against another and the 8 seeds will determine a playoff winner. I have defined the variables containing the seeds with the conference and the probabilities with the tickers.Is there some way I can get the probability referring to the seeds?(As to write East_Seed_1_prob_vs_East_Seed_8 in this case) Thanks guys, you're awesome

clc; clear all; close all;

letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M'];
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13];

string = 'ABCADEM';
answer = [];

for i = 1 : length(letters)
   indeces = strfind(string,letters(i));
   for j = 1 : length(indeces)
       answer(indeces(j)) = numbers(i);
   end
end

doubleAnswer = str2double(sprintf('',answer));

If you want the output to give the alphabetical order of the letters, 1 to 26, you can do this:

str = "ABCXYZ";
mat = char(str);
ds = double(mat) - 64

which gives

ds =  1     2     3    24    25    26
