access to struct fields based on struct name

Question

I have problem to access each field of struct in MATLAB. I tried to convert it to Cell however, it give me error :( How can I access each field with 2 loops ? I have wrote

Answer 1

You can access a structure dynamically with s.(fname) where fname is char variable. Note the ( ) around fname.

An example will clarify:

% Example structure
s.A = 10;
s.B = 20;

% Retrieve fieldnames
fnames = fieldnames(s);

% Loop with numeric index
for ii = 1:numel(fnames)
    s.(fnames{ii})
end

% ...or loop by fieldname directly
for f = fnames'
    s.(f{:})
end
