用于保存matlab工作区变量的文件叫做内存变量文件 .mat 也叫MAT文件

文本和字符

当您处理文本时，将字符序列括在双引号中。可以将文本赋给变量。

文本/字符序列
t = "Hello, world";

如果文本包含双引号，请在定义中使用两个双引号。

q = "Something ""quoted"" and something else."

q = 

    "Something "quoted" and something else."
字符串数组
>> A = ["a","bb","ccc"; "dddd","eeeeee","fffffff"]

A = 

  2×3 string 数组

    "a"       "bb"        "ccc"    
    "dddd"    "eeeeee"    "fffffff"

>> strlength(A)

ans =

     1     2     3
     4     6     7
字符数组使用单引号
数据类型为 char 的字符数组
>> seq = ‘GCTAGAATCC‘;
whos seq
  Name      Size            Bytes  Class    Attributes

  seq       1x10               20  char    
使用方括号串联字符数组
>> seq2 = [seq ‘ATTAGAAACC‘]

seq2 =

    ‘GCTAGAATCCATTAGAAACC‘
