Maybe this belongs to the bugs list or not to an Octave ("kernel") list at all:

The contributed script xcorr.m (in a subdir "imagep") can only process vectors, when
given to it two non-string parameters. For that it checks

if (is_matrix(x) || is_matrix(y))
      error("Only vectors are supported, use xcorr2 for matrix correlation");
    end
    
Shouldn't that read "!is_vector(x)" instead of "is_matrix(x)", simply because a
vector is a (special) matrix, too?
