If you want to change both variables at the same time, then you do not need two loops. Just ibe loop, where both variables are made to change as the loop increments. This could be done with a mathematical _expression_ or an index:

for ind = 1:3
  a = ind;
  b = 9 + ind;
  printf ("a = %i, b = %i\n", a, b);
endfor

a = 1, b = 10
a = 2, b = 11
a = 3, b = 12

Or

a = [1,2,3];
b = [10,11,12];

for ind = 1:3
  printf ("a = %i, b = %i\n", a(ind), b(ind));
endfor

a = 1, b = 10
a = 2, b = 11
a = 3, b = 12
