Use a blank list of join words

Join character vector cell arrays with delimiters

Join character vectors using multiple different delimiters

---

        strjoin The function of the function is to join strings in an array .

grammar

str = strjoin(C)
str = strjoin(C,delimiter)

explain

str = strjoin(C) By way of C The elements of are linked with spaces between consecutive elements , structure str.C It can be a character vector cell array or a string array .
str = strjoin(C,delimiter) By way of C Each element of the delimiter To construct str.

Example

Use a blank list of join words

         Use a single white space to join the character vector cell array C Each character vector in .

C = {'one','two','three'};
str = strjoin(C)


str = 
'one two three'

Join character vector cell arrays with delimiters

         Join the character vectors in the cell array into a character vector . Specify a comma followed by a space character as the separator .

C = {'Newton','Gauss','Euclid','Lagrange'}

C = 1x4 cell
    {'Newton'}    {'Gauss'}    {'Euclid'}    {'Lagrange'}

%%

str = strjoin(C,', ')

str = 
'Newton, Gauss, Euclid, Lagrange'

Join character vectors using multiple different delimiters

         Specify several different delimiters in the character vector cell array .delimiter The cell array must contain more elements than C The number of elements contained is less than one .

C = {'one','two','three'};
str = strjoin(C,{' + ',' = '})

str = 
'one + two = three'

Input parameters

C - Input text

         Input text , Designated as 1×n Character vector cell array or string array .

delimiter - Separator character

Separator character , Specify as character vector 、1×n Character vector cell array or 1×n Array of strings .

• If delimiter Is a character vector , be strjoin By means of C Insert delimiter To form str.delimiter The input can include any of the following escape sequences ：

  \\	The backslash
  \0	Null value
  \a	alert
  \b	Back space
  \f	Page identifier
  \n	A newline
  \r	A carriage return
  \t	Horizontal tabs
  \v	Vertical tabs

• If delimiter Is an array of character vector cells , Then it must contain more elements than C The number of elements contained is less than one . Each element in a cell array must be a character vector .strjoin Insert by interleaving delimiter and C To form str.delimiter All characters in are inserted as literal text , Escape sequence is not supported .

Tips

• from R2016b Start , It is recommended to use join Function to join the elements of a string array .
