在Matlab中，对于多输入功能，如何将单个输入用作多个输入? [英] In Matlab, for a multiple input function, how to use a single input as multiple inputs?

问题描述

我有一个函数，它接受可变数量的输入，例如myfun(x1,x2,x3,...).

I have a function that takes a variable number of inputs, say myfun(x1,x2,x3,...).

现在，如果我将输入存储在结构数组S中，我想做类似的事情 myfun(S.x1,S.x2,...).我该怎么做?

Now if I have the inputs stored in a structure array S, I want to do something like myfun(S.x1,S.x2,...). How do I do this?

推荐答案

您可以首先使用

You can first convert your structure to a cell array using STRUCT2CELL, and then use that to generate the list of multiple inputs.

S = struct('x1','something','x2','something else');
C = struct2cell(S);
myfun(C{:});

请注意，在S中定义字段的顺序是传递输入的顺序.要检查字段的顺序是否正确，可以在S上运行fieldnames，这将返回一个字段名称与C中的值相对应的单元格.

Note that the order in which the fields in S are defined are the order in which the inputs are passed. To check that the fields are in the proper order, you can run fieldnames on S, which returns a cell with field names corresponding to the values in C.
