i have two loops like this:
in the first loop i calculate x (for example) and in the second i calculate y, but in each iteration x depends on y.
for i=1:10
x=.....;
% here i will get the result fo i=1 but i must simultanously use it in the second loop
end
%second loop
for i=1:10
y=....;
end

You can merge both the loops and use the result in the same iteration
for i=1:10
x = 10*i; % This is the value generated
y = x + 1; % Using generated value x to evaluate y
end

for i = 1:10
a = rand+rand ; % this is the result in first loop
for j = 1:3
b = a+rand ; % result of first loop used in second loop
end
end

Merge both the loops and use the generated result in the same loop.
for i=1:10
x = 10*i; % This is the value generated. Expression on the RHS is a random one
y = x + 1; % Using generated value x to evaluate y
end
Hope this helps
