if true
  % code
parfor throw_1 = 1:1:6
    for throw_2 = 1:1:6   
        RollTotal = throw_1 + throw_2;
        NumbersThrownCount(RollTotal) = NumbersThrownCount(RollTotal) + 1;       
    end  
end
  end

I am having problems with this code, I am trying to use a parfor but I am getting a variable classification error any help on how to fix this would be amazing.

Hi,

It’s my understanding that you are trying to use the parfor loop and trying to avoid the variable classification error. Following is the code for the same:-

NumbersThrownCount = zeros(12,1);
if true
    % code
    for throw_2 = 1:1:6
        temp = zeros(6,1);
        parfor throw_1 = 1:1:6
            RollTotal = throw_1 + throw_2;
            temp(throw_1) = RollTotal;
        end
        NumbersThrownCount(temp) = NumbersThrownCount(temp) + 1;
    end
end
