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

Why does sort not work for you? Are you looking for something more like rowsort?

[Adam]

'ascending, max, descending' is not uniquely defined for a vector of values. Can you give an example of what kind of logic you expect such a function to use?

[Mohammed AlThani]

for example

a = [2 5 4 1 3]

I want to arrange it like

a = [1 3 5 4 2]

[Adam]

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).

[Mohammed AlThani]

yes, kind of.

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

[Bob Thompson]

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]
