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

Question

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?

Answer 1

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);
