erase

Create a string array and delete substrings from it.

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

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

Delete the substring "the " from str. The erase function deletes both instances.

newStr = erase(str,"the ")

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

Delete multiple substrings from str.

match = ["the ","quick ","lazy "];
newStr = erase(str,match)

newStr = 2x1 string
    "brown fox jumps"
    "over dog"

Create a string array of file names, including full paths.

str = ["C:\Temp\MyReport.docx";
       "C:\Data\Experiment1\Trial1\Sample1.csv";
       "C:\Temp\Slides.pptx"]

str = 3x1 string
    "C:\Temp\MyReport.docx"
    "C:\Data\Experiment1\Trial1\Sample1.csv"
    "C:\Temp\Slides.pptx"

Delete the paths, leaving only file names. To match paths, create a pattern using the wildcardPattern function that matches all text that includes a final "\" character. Use that pattern with the erase function.

match = wildcardPattern + "\"

match = pattern
  Matching:

    wildcardPattern + "\"

filenames = erase(str,match)

filenames = 3x1 string
    "MyReport.docx"
    "Sample1.csv"
    "Slides.pptx"

For a list of functions that create pattern objects, see pattern.

Create a character vector. Delete the substring, ' World', including the space character.

chr = 'Hello World'

chr = 
'Hello World'

newChr = erase(chr,' World')

newChr = 
'Hello'
