Using a vector in an If statement for comet plot

I have a matrix that represents a total score for each round. I want to form a loop that goes through the matrix with a nested If statement for if the first element is odd, then playerBscore gets +1 and if first element is even, then playerAscore gets +1 and so on throughout the matrix so I can plot the function for each round on comet. I'm not sure what to set the initial playerBscore and playerAscore as either.
