Ideally I want to try and use flow control to replace max in finding the maximum number in an array

Try this -- it's one of the first, basic things you learn in programming:

y = rand(20,40);
[rows, columns] = size(y);
yMax = -inf;
rowOfMax = 1;
colOfMax = 1;
for column = 1 : columns
  for row = 1 : rows
    if y(row, column) > yMax
      yMax = y(row, column);
      rowOfMax = row;
      colOfMax = column;
    end
  end
end
fprintf('The max of y is %f.\nIt appears in row %d, column %d.\n', yMax, rowOfMax, colOfMax);
