suppose this function

# foo.m
function y = foo (s, x)
   warning("%d: %s\n", s.index, s.message) ;
   y = NaN;
endfunction

is in your path. Then executing

octave -f --eval 'pkg load parallel ; parcellfun (2, "factorial", {-1,2,-3},
"ErrorHandler", @foo);'

gives

warning: 3: 
warning: 1: 

Doing instead

octave -f --eval 'cellfun ("factorial", {-1,2,-3}, "ErrorHandler", @foo);'

gives the expected result

warning: 1: factorial: all N must be real non-negative integers
warning: 3: factorial: all N must be real non-negative integers
