how to increase two variables in a for loop at the same time

for theta_inf_1 = 7:2:15
for theta_inf_2 = 15:-2:7
    
    
    
    
    
    
    
    
    
end
end

How can I increase these loops at the same time. I mean when the theta_inf_1 = 7, theta_inf_2 = 15, and also when theta_inf_1 = 9, theta_inf_2=13. Thank you.

In general:

theta_inf_1_values = 7:2:15;
theta_inf_2_values = 15:-2:7;

for ii = 1:numel(theta_inf_2_values)
    disp(ii)
    theta_inf_1 = theta_inf_1_values(ii)
    theta_inf_2 = theta_inf_2_values(ii)
    
    % the rest of your loop
    
end

     1

theta_inf_1 = 7

theta_inf_2 = 15

     2

theta_inf_1 = 9

theta_inf_2 = 13

     3

theta_inf_1 = 11

theta_inf_2 = 11

     4

theta_inf_1 = 13

theta_inf_2 = 9

     5

theta_inf_1 = 15

theta_inf_2 = 7

(In this particular case, theta_inf_1 == 22-theta_inf_2 so you could use that relation instead.)
