dff1 = [];
dff2 = [];
dff3 = [];
dff4 = [];
num_dff = rand(5121,2);
wholedff = {dff1, dff2, dff3, dff4};
for i = 1:length(wholedff)
wholedff{i} = num_dff
end
This code gives me the values I'd like to see but in the 1x4 cell wholedff, not in the single dffs (dff1, dff2, dff3, dff4), which remain empty. How do I create this link? Thanks!

dff1=wholedff{1};
dff2=wholedff{2};
...
but why would you want to do that? That is why we do indexing so we do not have to have so many variables.

Instead of assigning variables to them, do the operations using wholedff{1} or wholedff{2}. For example:
wholedff{1}=[wholedff{1},5]*10;
No need for a bunch of variables.
