在Matlab中动态访问嵌套字段

Question

(如何)我可以动态访问Matlab中的嵌套字段吗？我在考虑像这样的测试用例:

a = struct;
a.foo.bar = [];

place = {'foo', 'bar'};

a.(place{:})

% instead of the following, which only works if know in advance
% how many elements 'place' has
a.(place{1}).(place{2})

Answer 1

一个我不太满意的解决方案,主要是因为它缺乏.( )动态字段名称语法的优雅,是:

getfield(a, place{:})
