ARPACK interface for octave 2.9.x

[David Bateman]

Dear All,

Please find attached my first try at an interface to ARPACK for the 
2.9.x sparse type, that implements only the eigs function. It seems to 
work for the basic eigs(A), but I definitely know it won't work in many 
other cases. In particular many of the additional arguments (eg 
opts.cholB, opts.permB, B) are either ignored or probably treated 
incorrectly. Basically I know nothing of the use of ARPACK and so am 
looking for someone who might have some good test cases for all of the 
functionality of eigs, and if motivated to help in debugging the rest of 
this stuff, and so sending this function to the list is a request for 
help...

Enjoy
David
