Index in position 1 exceeds array bounds (must not exceed 1). How do I fix this error?

n = input('Number of dice: '); %number of dice being rolled
numberOfExperiments = input('Number of trials: '); 
faces = input('Number of faces: ');

a = {'G1' 'g1'}
b = {'G2' 'g2'}

X = randn(numberOfExperiments, 2)

for rows = 1:numberOfExperiments
    i =randperm(length(a),1)
    A=a(i)
    B=b(i)
    Anew = cell2mat(A)
    Bnew = cell2mat(B)
    for cols = 1:2
        C(:,cols) = X(Anew, Bnew)
    end
    C(rows, :) = X(Anew, Bnew)
end

What is the purpose of a and b? And what is faces used for? You never use it. Put in some comments to explain it to us. Often if you put in comments, you'll realize the error on your own.

Anew and Bnew are not integers, you define a and b as cells with chars then use cell2mat but they are still not integers so you'll get an error. You can't use chars for indexing.

Also just like Image Analyst suggested, comments would help help both you and the person that's tryin to help 😃😄
