Problem 43686. Apply Function to Each Field of a Structure Array: Part 2
The builtin structfun applies a function handle to each field of a scalar structure, but it does not work for structure array. The purpose of this problem is to generalize structfun to enable support for structure array input.
Write your own function structfun2 which accepts a structure array s and a function handle f as the inputs. The output c = structfun2(f,s) is a structure array c of the same size and same fields as s, where each field of the structure element of c stores the result of f applied to the same field of the relevant structure element in s. The structfun2 must preserve the behavior of structfun for scalar structure input. That is, when s is a scalar structure, your output reduces to c = structfun(f,s,'UniformOutput',false). No assumption on f is needed in this problem.
Example:
s = struct('f1',{1, [3 4]; 1, [5 6]},'f2',{[1 2], 2; [3 4 5], [2 5]}); f = @numel; c = struct('f1',{1, 2; 1, 2},'f2',{2, 1; 3, 2});
