insertAfter

Insert string after specified substring

Syntax

newStr = insertAfter(str,startStr,newText)

newStr = insertAfter(str,startPos,newText)

Description

newStr= insertAfter(str,startStr,newText)insertsnewTextintostrafter the substring specified bystartStrand returns the result asnewStr. IfstartStroccurs multiple times instr, theninsertAfterinserts text after every occurrence ofstartStr.

Ifstr是一个字符串array or a cell array of character vectors, theninsertAfterinsertsnewTextinto each element ofstr. The output argumentnewStrhas the same data type asstr.

example

newStr= insertAfter(str,startPos,newText)inserts the text specified bynewTextintostrafter the position specified bystartPos.

Insert Text After Substring

Open Live Script

Create string arrays and insert text after substrings.

Starting in R2017a, you can create strings using double quotes.

str ="The quick fox"

str = "The quick fox"

Insert text after the substring"quick".

newStr = insertAfter(str,"quick"," brown")

newStr = "The quick brown fox"

Insert substrings into each element of a string array. When you specify different substrings as positions, they must be contained in a string array or a cell array that is the same size asstr.

str = ["The quick fox jumps";"over the dog"]

str =2x1 string array"The quick fox jumps" "over the dog"

newStr = insertAfter(str,["quick";"the"],[" brown";" lazy"])

newStr =2x1 string array"The quick brown fox jumps" "over the lazy dog"

Insert Substring After Position

Open Live Script

Create string arrays and specify positions to insert substrings.

Starting in R2017a, you can create strings using double quotes.

str ="James Maxwell"

str = "James Maxwell"

Insert a substring after the fifth character.

newStr = insertAfter(str,5," Clerk")

newStr = "James Clerk Maxwell"

Insert substrings into each element of a string array. When you specify different positions with numeric arrays, they must be the same size as the input string array.

str = ["James Maxwell";"Carl Gauss"]

str =2x1 string array"James Maxwell" "Carl Gauss"

newStr = insertAfter(str,[5;4],[" Clerk";" Friedrich"])

newStr =2x1 string array"James Clerk Maxwell" "Carl Friedrich Gauss"

Insert Text After Position in Character Vector

Open Live Script

创建一个特征向量和之后插入文本specified position.

chr ='mushrooms and onions'

chr = 'mushrooms and onions'

Insert text after the ninth position.

newChr = insertAfter(chr,9,', peppers,')

newChr = 'mushrooms, peppers, and onions'

Insert text after a substring.

newChr = insertAfter(chr,'mushrooms',', peppers,')

newChr = 'mushrooms, peppers, and onions'

Input Arguments

`str`—Input text
string array|character vector|cell array of character vectors

Input text, specified as a string array, a character vector, or a cell array of character vectors.

Data Types:string|char|cell

`startStr`—Substring to insert text after
string array|character vector|cell array of character vectors

Substring to insert text after, specified as a string array, a character vector, or a cell array of character vectors.

Ifstr是一个字符串array or a cell array of character vectors, thenstartStrcan be a character vector, a string scalar, or a string array or a cell array of the same size asstr.

Data Types:string|char|cell

`startPos`—Start position to insert text after
numeric array

Start position to insert text after, specified as a numeric array.

Ifstr是一个字符串array or a cell array of character vectors, thenstartPoscan be a numeric scalar or a numeric array of the same size asstr.

`newText`—Text to insert
string array|character vector|cell array of character vectors

Text to insert, specified as a string array, a character vector, or a cell array of character vectors.

Ifstr是一个字符串array or a cell array of character vectors, thennewTextcan be a character vector, a string scalar, or a string array or a cell array of the same size asstr.

Data Types:string|char|cell

Output Arguments

`newStr`— Output text
string array | character vector | cell array of character vectors

Output text, returned as a string array, a character vector, or a cell array of character vectors.strandnewStrhave the same data type.

Data Types:string|char|cell

Extended Capabilities

Tall Arrays
Calculate with arrays that have more rows than fit in memory.

This function fully supports tall arrays. For more information, seeTall Arrays.

C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

str,startStr, andnewTextmust be a string scalar, a character vector, or a cell array containing not more than one character vector.

Distributed Arrays
Partition large arrays across the combined memory of your cluster using Parallel Computing Toolbox™.

This function fully supports distributed arrays. For more information, seeRun MATLAB Functions with Distributed Arrays(Parallel Computing Toolbox).
