octave/matlab-将字符串转换为唯一单词的矩阵 [英] octave/matlab - convert string into matrix of unique words

问题描述

在八度中，我想将字符串转换为字符串矩阵.说我有一个字符串:

In Octave, I want to convert a string into a matrix of strings. Say I have a string:

s = "one two three one one four five two three five four"

我想将其拆分为一个矩阵，使其看起来像:

I want to split it into a matrix so that it looks like:

one
two
three
four
five

已删除重复项.

此代码:

words = strsplit(s, ",") %Split the string s using the delimiter ',' and return a cell string array of substrings

只需创建一个与s完全相同的矩阵words.

Just creates a matrix words into exactly the same as s.

如何将字符串转换为唯一单词的矩阵?

How to I convert my string into a matrix of unique words?

推荐答案

以下内容也可以实现这一点:

The following will also accomplish that:

unique(regexp(string, '[A-z]*', 'match'))

或者，或者，

unique(regexp(s, '\s', 'split'))

与Werner的解决方案基本相同，但是它节省了临时时间，并且在需要进行更复杂的匹配时更加灵活.

Basically the same as Werner's solution, but it saves a temporary and is more flexible when more complicated matches need to be made.
