我如何写保护Matlab语言？ [英] How can I write-protect the Matlab language?

问题描述

Matlab允许你覆盖内置的函数，而不会有太多的警告。例如，我用变量覆盖了函数 max（），但Matlab没有提示我对此。错误仅在函数调用后才抛出，并且不会帮助您看到实际问题：

  min = 0 ; 
 max = 10; 
 x = linspace（min，max，20）; 
 y = exp（x）; 
 disp（['value is：'，num2str（max（y））]] 
  

错误消息：

 下标索引必须是真正的正整数或逻辑。 
  

有没有办法在启动时或写入时保护所有的Matlab语言一个设置文件，以防止这种情况发生？

解决方案

截至9/2015，我还没有找到一种方法来<保存原生matlab函数/语言，在启动时将其设置为/ flag / etc。

如果您关心某个特定函数，那么有多种方式可以查看它们是否被隐藏，包括Luis Mendo的回答： which（'name_of_function'，'-all'）。

如果将来发现某种方法，我会很乐意接受该答案！

Matlab allows you to overwrite built in functions without so much as a warning.

For example, I've overwritten the function max() with a variable, but Matlab doesn't alert me to this. An error is only thrown later when the function is called, and doesn't help you see the actual problem:

min     = 0;
max     = 10;
x       = linspace(min,max,20);
y       = exp(x);
disp(['the value is: ', num2str(max(y))])

Error message:

Subscript indices must either be real positive integers or logicals.

Is there a way to write-protect all of the Matlab language at startup, or in a settings file to prevent this?

解决方案

As of 9/2015, I have not found a way to easily write protect native matlab functions/language, as a setting/flag/etc at startup.

If you are concerned about a particular function, there are various ways to see if they are shadowed, including Luis Mendo's answer: which('name_of_function', '-all').

If a method is found in the future, I will gladly accept that answer!
