Re: More DLD mysteries

Al,
   At first glance, it looks like an argument gets passed to 'any' or 
'all', if you don't want to specify a dimension, pass -1 (see 
src/data.cc ANY_ALL macro). They both also reduce the dimensionality by 
one, similar to when we do max(max(some_2d_matrix)), so if your mattrix 
is 2d, use any/all twice and then use then index the "top-left" item of 
the bools matrix returned.

Hope this helps,

JD
