Changing Function number every loop

I am trying to figure out what is the best way to change a value n every time I use this function in another loop. I would like n to be 4, then 8, then 12, and then 16. n = [4; 8; 12; 16] I have this specified on another main script using this function. It is being looped 4 times using each of these values. Thank you!

function outpt=TargetRand(n, search, target)

%n=number of x's and o's you want plotted;

%search='c' or 'f'; 'c' means conjunctive search, 'f' means feature search

%target= 'y' or 'n' for presence of target in image;

%h=figure;

%pause

%h725=get(h,'CurrentCharacter');

x=rand(n, 1);

y=rand(n,1);

z=rand(2,1);

if(z(1) <= 0.5)

target_sym='X';

not_target='O';

else

target_sym='O';

not_target='X';

end

if(z(2) <= 0.5)

target_col='r';

not_col='g';

else

target_col='g';

not_col='r';

end

if(strcmp(target, 'y') && strcmp(search, 'f'))

g=text(x(1), y(1), target_sym);

set(g, 'color', target_col);

for i=2:n

g=text(x(i), y(i), not_target);

set(g, 'color', target_col);

end

elseif(strcmp(target, 'n') && strcmp(search, 'f'))

for i=1:n

if(i<=n/2)

char='X';

else

char='O';

end

g=text(x(i), y(i), char);

set(g, 'color', target_col);

Seems would be just call it in a loop or even with arrayfun...

search='c';
target='y';
N=[4:4:16].';
ret=arrayfun(@(n)TargetRand(n,search,target),N);

for a fixed set of the other parameters buried inside the anonymous function.

If they also vary by iteration, then pass them, too, or use an explicit for...end loop.
