Hi, I have a struct type array:
subtree(1).Parent= [2 2 2]
subtree(1).Children= [1 2 3; 3 2 4]
subtree(2).Parent= [1 2 2]
subtree(2).Children= [1 2 3; 5 5 5]
My question is, if I know the Parent value=[2 2 2] and I don't know the subtree index, how can I find/search its children=[1 2 3; 3 2 4]? In another words how I can get the index of the subtree that contain Parent= [2 2 2]

It depends on how "parent value" and "its children" is defined. Are you looking for the subtree index of e.g. [2,2,2] or do you want to obtain all column values of the Children fields for all Parent values like 2? Please post a meaningful example.

TargetParent = [2 2 2]
TF = arrayfun(@(k) isequal(subtree(k).Parent, TargetParent), 1:numel(subtree)) % logical indices
IDX = find(TF) % convert to linear indices

You can convert linear indices to subindices using IND2SUB
[i,j] = ind2sub(size(subtree),IDX)
