Build an array with different column lengths

Have one large data set (3333x1 double) and am trying to section out rows based on certain index values. If I have say 10 index pairs (beginning and end row) that I want to section out,each with different lengths how can I build one new nx10 matrix?
I keep getting subscripted assignment mismatches and similar errors when I try things like:
for i = 1:length(indices)
newData(:,i) = olddata(indexstart(i):indexstop(i),:);
end

Usually you would store such a result as a cell array,
newData=cell(1, length(indices));
for i = 1:length(indices)
newData{i} = olddata(indexstart(i):indexstop(i));
end
If it needs to be a numeric array, you need to decide what will go in the missing spots.
