Tree Structure For a Cell Array

Hi,

I am trying to generate a code which creates a tree of a cell array. I have a 6x4 cell array. I want the first column to be the parent nodes and subsequent columns to be child nodes of the previous column. I was able to find a code but it makes my entire cell array a parent node. I have been trying to modify it but am having troubles. Below is the code, any help will be much appreciated! Thanks!

function [treearray, nodevals] = getTreeArray(cellarray)

[nodes, ~, nodevals] = treebuilder(cellarray, 1);

treearray = [0, nodes];

function [out, node, nodevals] = treebuilder(cellarray, rnode)

out = []; nodevals = {};

% Start node off at root node

node = rnode;

[rows, columns] = size(cellarray);

for jj = 1:columns

for ii = 1:rows

node = node + 1;

if iscell(cellarray{ii})

[tb, node, nv] = treebuilder(cellarray{ii}, node);

out = [out, rnode, tb];

nodevals = [nodevals, nv];

else

out = [out, rnode];

nodevals = [nodevals, {node; cellarray{ii}}];

end

end

end

end

end
