动态变量名称在matlab中 [英] dynamic variable names in matlab

问题描述

我希望从另一个结构（ BT ）扩展一个结构（ bac ）。这些字段的名称包含在单元格数组中（添加）作为字符串。

I wish to expand a structure (bac) with a number of fields from another structure (BT). The names of these fields are contained in the cell array (adds) as strings.

这是我拥有的现在（显然不做这个工作，解释这个帖子）：

this is what i have now (and obviously doesn't do the job, explaining this post):

for i=1:numel(adds)
    eval(genvarname('bac.',adds{i})) = eval(strcat('BT.',adds{i}));
end

我还尝试使用 sprintf ，似乎没有为我工作。我感到自信有一个人知道如何做，因为我觉得这应该很简单。

I also tried using sprintf, which did not seem to work for me. I feel confident one of you knows how to do it, since I feel it should be rather easy.

推荐答案

最好的方法这样做是使用动态字段名称：

The best way of doing this is to use dynamic field names:

for i=1:numel(adds)
    bac.(adds{i}) = BT.(adds{i});
end
