清理字符串以在Matlab中进行比较 [英] Sanitize string for comparison in Matlab

问题描述

这是来自

This is a follow-up question from this that considered evalc, instead of figgling with file-descriptors manually. You can see below an example about poor sanitization. I want to remove things such as trailing characters, all whitespaces, all newlines etc -- that usually cause unexpected things -- is there a ready sanitization command to do this?

EDU>> a

a =

1 +1*{x} -1*{y}*{z}


EDU>> b

b =

1 +1*{x} -1*{y}*{z}

EDU>> isequal(a,b)

ans =

     0

推荐答案

我不知道是否存在任何现成的健壮实现，但是效果很好

I don't know whether there exist any ready robust implementation but this works pretty well

xx=@(x)regexprep(x,'\s',''); isequal(xx(a),xx(b))

我在其中使用匿名功能并删除了一些奇怪的地方，例如通常在窗口上很难看到的尾随空格/换行符.

where I use anonymous function and remove some oddities such as trailing whitespaces/newlines often hard to see on the window.

此外，strtrim()和deblank()之类的命令对于删除尾随字符也很有用.

Also, the commands such as strtrim() and deblank() can be useful to you in removing trailing characters.
