    Inner product over one dimension

    c = sum_i a_i * b_i
    ', BadDoc => 'If a() * b() contains only bad data, c() is set bad. Otherwise c() will have its bad flag cleared, as it will not contain any bad values.', ); # pp_def( inner )

    pp_def( 'outer', HandleBad => 1, Pars => 'a(n); b(m); [o]c(n,m);', Code => 'loop(n,m) %{ $c() = $a() * $b(); %}', BadCode => 'loop(n,m) %{ if ( $ISBAD(a()) || $ISBAD(b()) ) { $SETBAD(c()); } else { $c() = $a() * $b(); } %}', Doc => ' =for ref
