Create string arrays and select text that occurs after substrings.

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

str ="The quick brown fox"

str = "The quick brown fox"

Extract the substring that occurs after the substring“快”. TheextractAfterfunction selects the new text but does not include“快”in the output.

newStr = extractAfter(str,“快”)

newStr = "brown fox"

Create a new string array from the elements 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 as the input string array.

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

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

newStr = extractAfter(str,[“快”;"the "])

newStr =2x1 string array"brown fox jumps" "lazy dog"

You also can specify one substring as a position that is applied to all elements of the input string array.

Create strings after specified positions.

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

str ="Edgar Allen Poe"

str = "Edgar Allen Poe"

Select the substring after the 12th character.

newStr = extractAfter(str,12)

newStr = "Poe"

Select substrings from 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 = ["Edgar Allen Poe";"Louisa May Alcott"]

str =2x1 string array"Edgar Allen Poe" "Louisa May Alcott"

newStr = extractAfter(str,[12;11])

newStr =2x1 string array"Poe" "Alcott"

Select substrings from each element and specify the same position.

newStr = extractAfter(str,6)

newStr =2x1 string array"Allen Poe" " May Alcott"

Create a character vector. Then create new character vectors that are substrings ofchr.

chr ='peppers and onions'

chr = 'peppers and onions'

Select text after the 12th position.

newChr = extractAfter(chr,12)

newChr = 'onions'

Select text after a substring.

newChr = extractAfter(chr,'and ')

newChr = 'onions'
