Yes, they aren't implemented in octave or matlab R14 for that matter.

Ok this is a bug in assert.m, as it shouldn't try to do a subtraction
when the tolerance is zero. Rather it should do a compare.... I'd=20
suggest a patch like, that attached. I haven't committed it however
as its upto Paul to decide what he whats done in this case.

Cheers
