Can I pass a variable to the outside of a for loop after each iteration?

I am running a forloop and the jump for the for loop, n, is dependent upon a value generated within each turn of the loop.

for i = 1:n:100 for example, where after each iteration of the loop, the n changes value and would the jump distance would need to be different each time. For example, if it runs as i = 1, n = 3 at the end of the calculations, and then i would need to jump to i = 4, not to i = 2.

Is there any way this is possible? That value of needs to change with each iteration of the forloop run otherwise the program will not work.

Sure. For example,

n=3; i=1;
while i<200
    
    
    
    disp("i="+i+"  n="+n)
    
    i=i+n;
    
    n=ceil(2*log(i+n));

    
end

i=1  n=3
i=4  n=4
i=8  n=5
i=13  n=6
i=19  n=7
i=26  n=7
i=33  n=8
i=41  n=8
i=49  n=9
i=58  n=9
i=67  n=9
i=76  n=9
i=85  n=10
i=95  n=10
i=105  n=10
i=115  n=10
i=125  n=10
i=135  n=10
i=145  n=11
i=156  n=11
i=167  n=11
i=178  n=11
i=189  n=11

Note that this is a while loop, which is what I would use in this kind of situation.

If you are trying to use "for i" then do something like

nexti = 1;
for i=1:whatever
  if i < nexti; continue; end
  stuff
  n = something appropriate
  more stuff
  nexti = i+n;
end
