MATLAB:如何从2x1或nx1字符串中删除字符

Question

您好。

这里有一个2x1字符串：

A = ["CHAPTER 1. Random info in middle one, Random info still continues. 1";...
"CHAPTER 2. Random info in middle two. Random info still continues. 1"];

如何删除"；第#章"；，最后一个数字和空格后面的空格？这是我的尝试：

%PlanA
for n=1:2
% Delete "Chapter+Nr"
A(n,1) = erase(A,'(CHAPTER d)'); 
% Delete last nr 1 at end
A(n,1) = erase(A,'d'); 
end
%PlanB
A(strcmp(A, 'CHAPTER d')) = []

我不知道为什么这不起作用？

感谢您的帮助谢谢

您可以为此使用regexprep：

regexprep(A,'CHAPTER d+. (.+) d$','$1')
ans = 
2×1 string array
"Random info in middle one, Random info still continues."
"Random info in middle two. Random info still continues."
