I'm fairly new to Matlab, so this might be a simple question or one that just isn't possible. I have a bunch of data that was grabbed from a JSON file. For one particular field, there might have been one or more words in the JSON object for any given item. The problem is that the toolbox I used (JSONlab) made that field a character array if there was only one word, and a cell array if there were more than one word. I would like all of the fields for each item to be cell array, regardless of the number of words in that field. Is there a way to force character arrays to become cell arrays?
Here's what I've tried so far (data is a 1×6000 cell array with 5556 valid items):
for i = 1:5556 item = data{1,i}; categories = item.categories; if ischar(categories) item.categories = cellstr(categories); endend
This doesn't have any compile/run-time issues, but it doesn't actually change anything. For example, if the only thing in categories is "Mexican", then it's still a character array afterwards.
