如何在MATLAB中从字符串创建首字母缩写词？

[poster]

有没有一种简单的方法可以从MATLAB中的字符串创建首字母缩写词？例如：

'Superior Temporal Gyrus' => 'STG'

回答：

如果您想将每个大写字母都写成一个缩写...

...您可以使用功能REGEXP (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/regexpi.html) ：

str = 'Superior Temporal Gyrus'; %# Sample string abbr = str(regexp(str,'[AZ]')); %# Get all capital letters ...或者您可以使用UPPER (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/upper.html)和ISSPACE (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/isspace.html)函数：

abbr = str((str == upper(str)) & ~isspace(str)); %# Compare str to its uppercase %# version and keep elements %# that match, ignoring %# whitespace ...或者您可以改用ASCII / UNICODE值 (http://www.cs.utk.edu/~pham/ascii_table.jpg)来表示大写字母：

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


如果您想将每个单词的首字母缩写为...

...您可以使用功能REGEXP (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/regexpi.html) ：

abbr = str(regexp(str,'\w+')); %# Get the starting letter of each word ...或者您可以使用功能STRTRIM (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/strtrim.html) ， FIND (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/find.html)和ISSPACE (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/isspace.html) ：

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 (http://www.mathworks.com/access//helpdesk/help/techdoc/math/f1-85462.html#bq7egb6-1)修改以上内容，以避免调用FIND (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/find.html) ：

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


如果您想将每个单词的首字母大写缩写，

...您可以使用功能REGEXP (http://www.mathworks.com/access/helpdesk/help/techdoc/ref/regexpi.html) ：

abbr = str(regexp(str,'\
