Hello,
So if you do not know how large your 3 arrays are going to be and you want them to be exact size I suggest you do something like this:
firstarray={};
secondarray={};
thirdarray={};
for i=1:size(out,1)
if out{i,2}<0
firstarray{end+1}=out(i,1);
elseif out{i,2}==0
secondarray{end+1}=out(i,1);
else
thirdarray{end+1}=out(i,1);
end
end
This method is a little slow however since one of the arrays change size on every iteration. Hope this helps!
