显示 更早的评论
a=cell(10,1);
for n=1:10
a{n}=cell(3,1);
a{n}{1}=datestr( now() );
a{n}{2}=now();
a{n}{3}=n;
end
% OK
a{1}
{'06-Apr-2021 19:02:25'}
{[ 7.3825e+05]}
{[ 1]}
% OK
a{1}{1}
'06-Apr-2021 19:02:25'
% I would like to obtain by
b = a{1:10}{3}
1,2,,,,,,10 % array

If you really want to use inconvenient nested cell arrays, this will work with your example data:
b = [a{:}];
b = [b{3,:}]
Note that using just one cell array (no nested cell arrays) makes this task simpler:
a = cell(10,3);
for n = 1:10
a{n,1} = datestr( now() );
a{n,2} = now();
a{n,3} = n;
end
a{1,1}
a{1,2}
b = [a{:,3}]
