## @deftypefn {Function File} @var{rval}= {} strjoin(@var{prefixstr},@var{stringcell})
## @deftypefnx {Function File} @var{rval}= {} strjoin(@var{prefixstr},@var{varargs})
## joins the strings in @var{stringcell} with the @var{prefixstr} like the list-join
## function in Python; the second version allows usage with variable number of arguments.
## Note that, if using cell-array as a second argument, only 2 arguments are accepted.
## Also note that, both the arguments are strings or containers of strings (cells).
##
## @example
## @group
## strjoin(' loves-> ','marie','amy','beth')
## ##returns 'marie loves-> amy loves-> beth'
##
## strjoin('*',@{'Octave','Scilab','Lush','Yorick'@})
## ##returns 'Octave*Scilab*Lush*Yorick'
## @end group
## @end example
## @end deftypefn
## @seealso {strcmp}
