Ran in:
I have a cell array that needs to be sorted both ascending and descending.
It is:
Groups = {[-83;-84] [-65] [-47;-50] [-30;-33] [-22;-26] [-15;-16] [-6; -7]}
Groups = 1×7 cell array
{2×1 double} {[-65]} {2×1 double} {2×1 double} {2×1 double} {2×1 double} {2×1 double}

"What I mean is how can I organize G in this way?"
G = {[-6; -7] [-16;-15] [-26;-22] [-33;-30] [-50;-47] [-65] [-83;-84]};
Maybe like this:
G = {[-83;-84] [-65] [-50;-47] [-33;-30] [-26;-22] [-16;-15] [-6; -7]};
[~,idx] = sort(cellfun(@(x)max(abs(x)),G));
G = G(idx);
format compact
celldisp(G);
G{1} = -6 -7 G{2} = -16 -15 G{3} = -26 -22 G{4} = -33 -30 G{5} = -50 -47 G{6} = -65 G{7} = -83 -84

What are you sorting on? The average value of each array? If so, try this:
% Make an unsorted G
G = {[-6; -7] [-65] [-15;-16] [-30;-33] [-22;-26] [-47;-50] [-83;-84]}
% Find means
for k = 1 : numel(G)
theMeans(k) = mean(G{k}, 'all');
end
% Sort based on means:
[sortedMeans, sortorder] = sort(theMeans, 'descend')
% Now sort G
GSorted = G(sortorder)
celldisp(GSorted)

this works too, thanks!

OK, but you have said it works for multiple answers even though they sort it differently. I sorted by the average value and @_ sorted it by the max value. So which way is it? (In this particular case they're the same though.)

If by sort, you mean sort within each element of cell array:
G = {[-83;-84] [-65] [-50;-47] [-33;-30] [-26;-22] [-16;-15] [-6; -7]};
Ga = cellfun(@(x)sort(x, 'ascend'), G, 'uni', false);
Gd = cellfun(@(x)sort(x, 'descend'), G, 'uni', false);
Or if you mean overall, vertcat the cell array and then sort.

Hello,
I tried your answer and both Ga and Gd end up being the same.
What I mean is how can I organize G in this way?
G = {[-6; -7] [-15;-16] [-22;-26] [-30;-33] [-47;-50] [-65] [-83;-84]};
