How to store values from a for loop in an array/matrix?

I have this given 10x10 pixel image, and I would like to create a function that returns the column and row position that has the most red pixels.This is what I have so far, I am stuck on how to correctly store all the values and not just return the ending column and row. In addition if two columns or rows have the same amount it should return the lowest index value. Thanks for the help.

img = 'Image16.tif';
myImg = imread(img);
mySize = size(myImg);

redArr = myImg(:, :, 1);
greenArr = myImg(:, :, 2);
blueArr = myImg(:, :, 3);

isRed = (redArr == 255) & (greenArr == 0) & (blueArr == 0);
for i = 1:mySize(1)
    rowCount = (sum(isRed(i,:)));
    for j = 1:mySize(2)
        colCount = (sum(isRed(:,i)));
    end
end

'... given 10x10 pixel image,... returns the column and row position that has the most red pixels."

There is only one color value at each pixel? How can there be a maximum position location?

That's correct. The function wants the logical 1 or 0 maximum sum of the rows and columns of the image.

img = randi([0,1], 10, 10, 3) * 255;
imgIsRead = (img(:, :, 3) == 255);

[v1, index1] = max(sum(imgIsRed, 1))
[v2, index2] = max(sum(imgIsRed, 2))
