How do i copy a file to multiple directories based on a variable

for example.

I make multiple folders using a loop

nModels = 32;
for  i = 1:nModels
mkdir (['core',int2str(i)]);
end

THEN i want to copy an application into each of these folders

for  i = 1:nModels
copyfile MARCO64_500.exe 'core',int2str(i);
end

But this does not work.

end
