MATLAB Function Reference

strtrim

Remove leading and trailing white-space from string

Syntax

• S = strtrim(str)
  C = strtrim(cstr)
  

Description

S = strtrim(str) returns a copy of string str with all leading and trailing white-space characters removed. A white-space character is one for which the isspace function returns logical 1 (true).

C = strtrim(cstr) returns a copy of the cell array of strings cstr with all leading and trailing white-space characters removed from each string in the cell array.

Examples

Remove the leading white-space characters (spaces and tabs) from str:

• str = sprintf('  \t   Remove    leading white-space')
  str =
          Remove    leading white-space
  
  str = strtrim(str)
  str =
  Remove    leading white-space
  

Remove leading and trailing white-space from the cell array of strings:

• cstr = {'     Trim leading white-space';
          'Trim trailing white-space     '};
  
  cstr = strtrim(cstr)
  cstr = 
      'Trim leading white-space'
      'Trim trailing white-space'
