Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help tokenize”.

  TOKENIZE cuts a string into pieces, returning the pieces in a cell array
  Use as
    t = tokenize(str)
    t = tokenize(str, sep)
    t = tokenize(str, sep, rep)
    str = the string that you want to cut into pieces
    sep = the separator at which to cut (default is whitespace)
    rep = whether to treat repeating separator characters as one (default is false)
  With the optional boolean flag "rep" you can specify whether repeated
  separator characters should be squeezed together (e.g. multiple
  spaces between two words). The default is rep=1, i.e. repeated
  separators are treated as one.
