How to order variables by their size?

Hi all,

Assuming I have these time-points, marking the start of a condition... I have 3 conditions (names = A, B and C), each with 5 consecutive blocks starting at (onsets)...

So onset times of these conditions are:

onsets{1,1} = [7848        8477        9099        9699       10315]
onsets{1,2} = [10923       11548       12136       12748       13353]
onsets{1,3} = [4565        5359        5985        6580        7211]

These correspond to:

names{1,1} = "A"
names{1,2} = "B"
names{1,3} = "C"

i.e. A_onsets = [7848 8477 9099 9699 10315]

As can be seen, when I sum these time-points (of onsets), the order of presentation was actually C, A, B.

sum_A = 45438        %sum_A = sum(onsets{1,1}))
sum_B = 60708        %sum_B = sum(onsets{1,2})
sum_C = 29700        %sum_C = sum(onsets{1,3})

How can I return an array of the order of the presentation of the conditions... e.g. order = ["C", "A", "B"]

Many many thanks in advance :)

Try this:

[~,ix] = sort(cellfun(@sum, onsets));
Out = names(ix)

producing:

Out =

  1×3 cell array

    {["C"]}    {["A"]}    {["B"]}

This is beautiiful!

Thank you so much.
