How to convert a cell array of structures to array of structures

searchNode's nodeinfo is a cell array of structures.

nodeinfo = searchNode(neo4jconn, 'Comment')

nodeinfo.NodeData contains node data. It has a property key 'text'

>> nodeinfo.NodeData{1}.text

ans =

blahblah

Array of structures would be easier to work with and accesses can be vectorized

Please suggest a better than for loop:

s = size(nodeinfo.NodeData, 1);

for i = 1:s
    comments(i).text = nodeinfo.NodeData{i}.text;
end

For example to collect text of all comments is now one-liner

text = [comments.text]

How can a cell array of structures be vectorized like that?

As long as the structures in the cells have all the same fields and that these structures in the cells are either scalar or arrays with the same number of rows:

nodedata = [nodeinfo.NodeData{:}];
%or
nodedata = cell2mat(nodeinfo.NodeData);

Thank you Guillaume

Will cell2struct() for for you?

cell2struct(nodeinfo.NodeData, {'text'}, 2) will return s x1 struct array with field text

whereas for loop creates 1x s array of structures
