A string refers to a character array of 1xn. Individual characters are stored according to unicode encoding, with each character accounting for two bytes

In matlab, simply enclose the string you need to set with (').

Disp (): display strings

Size (): the length of the string to

Double (): displays the string as ASCII code

Char (): displays the ASCII code as a string

Multiple strings can form a character matrix, but the number of characters per line of the matrix must be equal.

Strcat (); strvcat () join by column

String lookup: strfind (); / / case-sensitive

String substitution: strrep ():

T=num2str (x): converts the number x to the string t

T=int2str (x): converts the integer x to a string, and if x is not an integer, forensics x first and then converts it to a string

X=str2num (s): convert character matrix s to numeric matrix

Str=mat2strr (mat): converts an array or matrix to a corresponding string

String execution: eval ()
