Is there a command ( like "sort" for example ) arranges vector elements ascending ,max, descending (humped shap)?

based on what logic though? If I had to guess I'd say you want values sorted alternating at the start and end, with the max in the middle (assuming an odd number of elements).

yes, kind of.
but as index increase the value increases too, till maximum ,then the opposit as index increases value decreases. " hump shaped arrangement"

How do you differentiate between [24531] and [13542]?

>> V = randi(99,1,23)
V =
93 68 76 74 39 65 17 70 4 28 5 10 82 69 32 95 4 44 38 76 79 19 49
>> Y = sort(V);
>> Z = [Y(1:2:end),fliplr(Y(2:2:end))]
Z =
4 5 17 28 38 44 65 69 74 76 82 95 93 79 76 70 68 49 39 32 19 10 4

Yes. Use sort.
e.g.
a = [1,3,2,4];
b = sort(a,'ascend');% b = [1,2,3,4]
c = sort(a,'descend');% c = [4,3,2,1]
