Assigning a value to a certain index according to whether it matches the conditions of an if statement

This may be a mouthful but I'll do my best to go into depth of what I'm trying to solve.

I have

function [m] = game(n)

Within this, I have a shuffled deck of 52 numbers (which is named A) that have populated a 2 x n+1 vector named numbers.

I also have another vector named sum_numbers that is the sum of each column

sum_numbers = sum(numbers, 1).

Now I need to add a value to a certain location according to whether it matches the following criteria: if the last number in the 2nd row of numbers is greater than 8 and any value within a certain column in sum_numbers is less than 18, a new value will be given to that same column within numbers. So in reality, numbers can be greater than 2 rows. (For this portion I have already created a working code)

I also have to take into account that more than one value may be given to that column subsequently (in order to reach 18 and above) so I have another vector initiated as zeros right now

hit = zeros(1, n)

What I have so far is

for i=1:n
    if numbers(2,end) >= 8
        if sum_numbers(1,i) < 18
            new = A((numbers*2)+3+(sum(hit)))
            numbers(3+hit,i) = new
        end 
    end
end

I have tried out my function but the above code does not seem to work because hit isn't populated.

I also don't know how to populate hit. hit should be a 1 x n+1 vector which shows the amount of values given to the respective column(s) that match the criteria so that the values in A are given in subsequent order if need be. (ex. if the 2nd column of numbers has the numbers 3 and 4, which add up to less than 18, it is hit with a 4 and then hit again with the next value 8 and thus the second column in hit should say 2 for 2 'hit' values).

This will do what you said in the first paragraph:

deck = randperm(52); % Shuffle the deck
% Define n
n = 15; % Whatever you want...
% Define "newValue"
newValue = 99; % Whatever you want...
% Distribute deck over 2 rows and n+1 columns
numbers = reshape(deck(1:2*(n+1)), 2, [])
% Sum the columns
columnSums = sum(numbers, 1)
% Check if lower right element (last number in second row) is more than 18
if numbers(2, end) > 8
  % Lower right element is more than 8.
  % Now see which column sums are less than 18
  columnsToReplace = columnSums < 18
  % Now replace both rows in numbers of these columns with newValue.
  numbers(:, columnsToReplace) = newValue;
end
% Print numbers to command window:
numbers
