-## @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'
