Please, upload it. I made the package Autoload: No, as discussed in a previous thread. I think that no package has the right to hijack functions of the Octave's core. Change this if you disagree. I had also to manually add the file flag_implicit_skip_nan.m from the nan pacakge. I reported this problem upstream: http://permalink.gmane.org/gmane.comp.gnu.octave.devel/7213 Rafael
