Have mm.m be this:
function r = mm()
r=[1 2 3]
end
And have nn.m be this:
function nn
% some code.
% Get r from mm():
r = mm;
end

Why don't you have the function, nn.m, output the value of r, then the function mm can use that value. That is the best way to do it.
Alternatively, look at the help for global
