如何在MATLAB中从字符串创建首字母缩写词?

问题描述

有没有一种简便的方法可以从MATLAB中的字符串创建首字母缩写词?例如:

Is there an easy way to create an acronym from a string in MATLAB? For example:

'Superior Temporal Gyrus' => 'STG'

推荐答案

如果您想将每个大写字母都放在缩写中...

......，您可以使用功能 REGEXP :

str = 'Superior Temporal Gyrus';  %# Sample string
abbr = str(regexp(str,'[A-Z]'));  %# Get all capital letters

...，或者您可以使用 UPPER 和 ISSPACE :

... or you could use the functions UPPER and ISSPACE:

abbr = str((str == upper(str)) & ~isspace(str));  %# Compare str to its uppercase
                                                  %#   version and keep elements
                                                  %#   that match, ignoring
                                                  %#   whitespace

...，或者您可以改为使用 ASCII/UNICODE值大写字母:

... or you could instead make use of the ASCII/UNICODE values for capital letters:

abbr = str((str <= 90) & (str >= 65));  %# Get capital letters A (65) to Z (90)

......，您可以使用功能 REGEXP :

... you could use the function REGEXP:

abbr = str(regexp(str,'\w+'));  %# Get the starting letter of each word

...，或者您可以使用 STRTRIM ，查找和 ISSPACE :

... or you could use the functions STRTRIM, FIND, and ISSPACE:

str = strtrim(str);  %# Trim leading and trailing whitespace first
abbr = str([1 find(isspace(str))+1]);  %# Get the first element of str and every
                                       %#   element following whitespace

...，或者您可以使用逻辑索引，以避免调用查找:

... or you could modify the above using logical indexing to avoid the call to FIND:

str = strtrim(str);  %# Still have to trim whitespace
abbr = str([true isspace(str)]);

......，您可以使用功能 REGEXP :

... you can use the function REGEXP:

abbr = str(regexp(str,'\<[A-Z]\w*'));
