Given a cell A, I can find the maximum length by
[s,d] = cellfun(@size,A);
out = max([s,d]);
But how do I find the elements in A that have the length given by out? For example, given the cell array consisting of {[7 8 9]} {[6 10]} {[4 5 6 7]} {[1 2 3 4]}, extract {[4 5 6 7]} and {[1 2 3 4]}, which each have a length of 4.

hello
here my suggestion
A = [{[7 8 9]} {[6 10]} {[4 5 6 7]'} {[1 2 3 4]'}];
[s,d] = cellfun(@size,A);
out = max([s,d],[],'all');
ind = find(d == out | s == out) ;
A_selected = A(ind)

Ran in:
C = {[7,8,9],[6,10],[4,5,6,7],[1,2,3,4]}
C = 1×4 cell array
{[7 8 9]} {[6 10]} {[4 5 6 7]} {[1 2 3 4]}
N = cellfun('length',C);
X = max(N)==N;
D = C(X)
D = 1×2 cell array
{[4 5 6 7]} {[1 2 3 4]}

[s,d] = cellfun(@size,A);
m = max([s,d],[],'all');
idx=s==m|d==m;
Anew=A(idx);
