Hi guys,
I have to extract some elements from some structures and each structure is in cell.
Here is the for loop I'm using right now:
for i = 1:3
ext(i,:) = Models{toextract(i,1), toextract(i,2)}.scores(:,toextract(i,3));
end
toextract is a matrix where i have the indices that i need
can I avoid the for loop somehow?
Thank you !

No, you cannot. The alternaternative is to use arrayfun() and co, but it just has an implicit loop. So I would say a loop is much better in this case.
