How can I capture all outputs in a cell array, if the function uses varargout and the number of outputs is dependent on the function parameters.
Let us create a function whose number of outputs depends on the number of input arguments: D = zeros(2,3,4); fun = @size; ...

How to access elements with same field names in an array of structures without using a loop?
You could possibly work something up using cellfun with a subsasgn call, but it would be ugly and needlessly complex.
