问题描述
我正在努力做到这一点:
I'm trying to accomplish this:
strcat('red ', 'yellow ', 'white ')
我希望看到红色黄色白色"，但是，我在命令输出上看到"redyellowwhite".需要采取什么措施来确保正确地连接空间?预先感谢.
I expected to see "red yellow white", however, I see "redyellowwhite" on the command output. What needs to be done to ensure the spaces are concatenated properly? Thanks in advance.
推荐答案
从matlab帮助页面获取strcat:
From the matlab help page for strcat:
"strcat忽略尾随的ASCII空格字符，并从输出中忽略所有此类字符.ASCII的空格字符为空格，换行符，回车符，制表符，垂直制表符或换页符，所有这些都返回true MATLAB isspace函数的响应.使用串联语法[s1 s2 s3 ...]保留尾随空格.strcat不会忽略作为字符串单元格数组的输入."
"strcat ignores trailing ASCII white space characters and omits all such characters from the output. White space characters in ASCII are space, newline, carriage return, tab, vertical tab, or form-feed characters, all of which return a true response from the MATLAB isspace function. Use the concatenation syntax [s1 s2 s3 ...] to preserve trailing spaces. strcat does not ignore inputs that are cell arrays of strings. "
