MATLAB中未定义的函数 [英] Undefined function in MATLAB

问题描述

我在最新的MATLAB版本中使用函数dtw，并且想调整它的几个部分。为了开始，我输入了：

 编辑dtw 
  

我将结果代码保存到名为dtw_Copy.m的文件中，并将函数的名称更改为 dtw_Copy 。使用一系列输入参数 x 和 y 在第90行附近遍历代码：

  [metric，varargin] = getmutexclopt（{'absolute'，'euclidean'，'squared'，'symmkl'}，'euclidean' ，varargin）; 
  

我收到一条错误消息：

对于'cell'类型的输入参数，未定义的函数'getmutexclopt'。

我也收到此错误消息如果我没有逐行浏览代码，并且在再次测试一组输入参数 x之后键入 dtw_Current（x，y） 和 y 。

运行时：

  help'getmutexclopt'
  

它是表示找不到 getmutexclopt 。我也试过：

 编辑'getmutexclopt'
  

但我被告知currentDirectory / getmutexcloptm.m不存在。

我试过了：

  which getmutexclopt 
  

我被告知找不到 getmutexclopt 。

在线搜索时，发现一个看起来很简单的资源，以排除这个错误。该资源建议确保安装工具箱。我不确定哪个工具箱支持函数 getmutexclopt ，因此我在网站。这会产生一条消息：您的搜索 - getmutexclopt - 与任何文档都不匹配。

该资源还建议验证用于访问该函数的路径。我按照指示操​​作，当我输入时：

  which -all getmutexclopt 
  
 
 
 
我收到： 
 
 
  currentDirectory \ matlab\toolbox\signal\signal\private\getmutexclopt.m％私信号给
  
这似乎表明函数在信号工具箱中，这是私人的？是否有可能仍然运行 dtw_Current（x，y）和/或逐行运行其内容？ 
 
是的，这个问题是因为函数 getmutexclopt 是一个私人功能。如果您希望从 dtw 的副本中安全地调用该函数，则需要制作该函数的副本。它似乎是一个基本功能（在命令窗口中键入 edit private / getmutexclopt.m ），因此您可以将它作为子函数添加到 dtw_Copy  /  dtw_Current 。
 
 
 
另见这个问题  - 不允许在搜索路径中添加私有函数。
 
I using the function dtw in the latest MATLAB release, and would like to tweak a few parts of it. To get started, I typed:
edit dtw
I saved the resulting code to file called dtw_Copy.m, and changed the name of the function to dtw_Copy as well. Going through the code line by line with a set of input parameters x and y, around line 90:
[metric, varargin] = getmutexclopt({'absolute','euclidean','squared','symmkl'},'euclidean',varargin);
I receive an error message:

  
Undefined function 'getmutexclopt' for input arguments of type 'cell'.
I also get this error message if I do not go through the code line by line, and simply type dtw_Current(x,y), after again testing a set of input parameters x and y.

Upon running:
help 'getmutexclopt'
it is indicated that getmutexclopt is not found. I tried also:
edit 'getmutexclopt'
But am told that currentDirectory/getmutexcloptm.m does not exist.

I tried:
which getmutexclopt
And am told that getmutexclopt is not found.

Searching online, I found a resource that seemed straight-forward in trouble-shooting this error.  The resource recommends to ensure the toolbox is installed. I am unsure which toolbox supports the function getmutexclopt, and so I type the function name into the website. This results in a message that: "Your search - getmutexclopt - did not match any documents."

The resource also recommends verifying the path used to access the function. I followed the instructions to do so, and when I typed:
which -all getmutexclopt
I receive:
currentDirectory\matlab\toolbox\signal\signal\private\getmutexclopt.m  % Private to signal
This seems to indicate that the function is in the signal toolbox, which is private? Is there a possibility to still run dtw_Current(x,y) and/or to run its contents line by line?
解决方案
Yes, this issue is because the function getmutexclopt is a private function. You'll need to make a copy of that function if you hope to safely call it from your copy of dtw. It appears to be a basic function (type edit private/getmutexclopt.m in your Command Window) so you may be able to add it as a sub-function to your dtw_Copy/dtw_Current.

See also this question – adding private functions to the search path is not allowed.
