strsplit

split a string into a vector of strings

Calling Sequence

v = strsplit(str,ind)
[v, matched_separators] = strsplit(str)
[v, matched_separators] = strsplit(str, matrix_of_strings, limit)
[v, matched_separators] = strsplit(str, regexp_pattern, limit)

Arguments

str

A character string to split

ind

a vector of stricly increasing indices in the interval [1 length(str)-1].

v

the resulting column vector of string (dimension >size(ind,'*')+1).

matched_separators

a column vector of the matched separators

matrix_of_strings

a matrix of strings to search in str

regexp_pattern

a regular expression pattern

limit

maximum of limit elements

Description

v = strsplit(str, ind) splits the string str into a vector of strings at the points given by the indices in ind (after each characters pointed to by the index in ind).

strsplit(str) returns same thing as strsplit(str,1:length(str)-1).

strsplit(str, regexp_pattern, limit) returns an column vector of strings, each of which is a substring of str formed by splitting it on boundaries formed by the case-sensitive regular expression pattern.

If there are n occurrences of pattern , the returned array will contain n+1 items.

For example, if there is no occurrence of pattern , an array with only one element will be returned. Of course, this is also true if str is empty.

If limit is set, the returned array will contain a maximum of limit elements with the last element containing the whole rest of string.

strsplit(str, matrix_of_strings, limit) , str is splitted on any of elements. It allows to split on different separators for users without regex knowledge.

If strsplit() is called with a second output argument, the column vector of the matched separators is returned.

Examples

S='strsplit splits a string into a vector of strings';
strsplit(S,[15 25 30])
ind=strindex(S,' ')
    
[r_1, r_2] = strsplit("abcd")
    
[r_1, r_2] = strsplit("root:x:0:0:root:/root:/bin/bash",":",5)
    
[r_1, r_2] = strsplit("abc,def:ijk,:lmo","/:|,/")
   
[r_1, r_2] = strsplit("abc,def:ijk,:lmo",[":";","])    
    
strsplit("abcdef2ghijkl3mnopqr6stuvw7xyz","/\d+/") 

[r_1, r_2] = strsplit("abcdef2ghijkl3mnopqr6stuvw7xyz","/\d+/",2)
