我如何通过一系列的参数数目未知的在MATLAB的函数吗？ [英] How can I pass a set of an unknown number of arguments to a function in MATLAB?

问题描述

当你有一个函数，变量参数号（如ndgrid），你怎么可以传递参数的任意列表，该功能？

when you have a function that takes a variable argument number (like ndgrid), how can you pass an arbitrary list of arguments to that function?

例如我想使它这样有时我传递两个向量ndgrid，走出两个矩阵，即

For example I want to make it so that sometimes I pass two vectors to ndgrid and get out two matrices, i.e.,

[X1,X2] = ndgrid(x1,x2);

但其他时候，我可能会有更多X的，所以我会想

But other times I might have more X's, so I'll want

[X1,X2,X3,X4] = ndgrid(x1,x2,x3,x4)

有什么样的结构，我可以用它来存储一个未知数量的参数列表，然后只给该列表功能？而且是有没有办法从一个函数检索所有的输出，当你不知道有多少会出现？

Is there any kind of structure I can use to store a list of an unknown number of arguments and then just give that list to a function? And is there a way to retrieve all of the outputs from a function, when you don't know how many there will be?

感谢。

推荐答案

使用 varargin ， nargin ， varargout 和 nargout 您可以轻松定义变量参数/输出功能。见附件MATLAB文档链接，varargin页面。其他人都在底部链接：

Using varargin,nargin, varargout and nargout you can easily define variable argument/output functions. See the attached MATLAB documentation link for the varargin page. The others are linked at the bottom:

编辑：BTW，不要嘟嘟我自己的号角，但它似乎被实现，就像我在快速和肮脏的注释呵呵呵曾建议

BTW, not to toot my own horn, but it seems to be implemented just as I had suggested in the "quick-and-dirty" comment hehehe
