在Matlab中动态访问嵌套字段 [英] Dynamical access to nested fields in Matlab

问题描述

(如何)可以动态访问Matlab中的嵌套字段?我在考虑这样的测试用例:

(How) Can I dynamically access nested fields in Matlab? I was thinking about a test case like this one:

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})

推荐答案

我不太满意的一个解决方案是:

One solution I am not very happy with, mainly because it lacks the elegance of the .( ) dynamical field names syntax, is:

getfield(a, place{:})
