Matlab convert struct to cell array of strings

Question

I want to convert a structure to a cell array where all the entries are converted to strings, including numbers. If I take the MATLAB example:

s = 
    category: 'tree'
      height: 37.4000
        name: 'birch'

I want to convert this to

c = 
    'tree'
    '37.4000'
    'birch'

where all entries are converted to strings, including numbers. The function struct2cell(s) will convert s to:

ans =
    'tree'
    [37.4000]
    'birch'

Is there a quick way of getting from s to c?

If you want to force everything to a string, you can use num2str with cellfun:

cellfun(@num2str, struct2cell(a), 'UniformOutput', false)

The result will be a cell array of strings.
