split a string into a vector of strings
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)
:str A character string to split : :ind a vector of stricly increasing indices in the interval `[1
length(str)-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 :
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 split 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.
