23 -## FIXME: this file is here to avoid conflicts with new Octave versions. Matlab
24 -## has recently added strplit function (used to exist in Octave only) but
25 -## their syntax is not compatible with ours. Rather than timing the
26 -## release of each octave forge package that used strsplit, a copy of the
27 -## old version was placed as private. Once the new Octave version is
28 -## released, this file can be removed, and the calls to strsplit fixed.

32 -## @deftypefnx {Function File} {[@var{cstr}] =} strsplit (@var{s}, @var{sep}, @var{strip_empty})
33 -## Split the string @var{s} using one or more separators @var{sep} and return
34 -## a cell array of strings. Consecutive separators and separators at
35 -## boundaries result in empty strings, unless @var{strip_empty} is true.
36 -## The default value of @var{strip_empty} is false.
37 -##
38 -## 2-D character arrays are split at separators and at the original column
39 -## boundaries.
40 -##
41 -## Example:
42 -##
43 -## @example
44 -## @group
45 -## strsplit ("a,b,c", ",")
46 -## @result{}
47 -## @{
48 -## [1,1] = a
49 -## [1,2] = b
50 -## [1,3] = c
51 -## @}
52 -##
53 -## strsplit (["a,b" ; "cde"], ",")
54 -## @result{}
