Is this function really needed? I mean, stuff like "nansum" can easily
be implemented using something like.

x(isnan(x)) = 0;
y = sum(x,dim)

True, this will make a copy of the matrix, but is that so painful?

Besides, I think the fact that the NaN package shadows Octave's
built-in functions is very dangerous and confusing, even though I
understand the motivation. I think this package should not be
installed by default.
