I have a 2 dimensional array using NArray and wish to sort the values based
on the values in column zero or row zero.
How can I achieve this using NArray? I can't even seem to get the basic sort
working:-
matrix.sort(0)
gives me a "..blah..:in `sort': undefined method `<=>' for nil:NilClass
(NoMethodError)"
I know I can supply a block to the sort method but the documentation, such
that it is at:-
http://narray.rubyforge.org/SPEC.en
isn't that informative and implies that the above line should work?
Any ideas greatly appreciated.
Cheers, Chris.
