New versions 3.0.1-1 of

arpack (source) / libarpack-devel / libarpack0

for cygwin are available in the Cygwin distribution:

New release from new upstream team

"This project is a joint project between Debian, Octave and Scilab
in order to provide a common and maintained version of arpack.
Indeed, no single release has been published by Rice university for
the last few years and since many software (Octave, Scilab, R, 
Matlab...) forked it and implemented their own modifications,
arpack-ng aims to tackle this by providing a common repository
and maintained versions."

ARPACK is a collection of Fortran77 subroutines designed to solve large
scale eigenvalue problems.

ARPACK software is capable of solving large scale symmetric,
nonsymmetric, and generalized eigenproblems from significant
application areas. The software is designed to compute a few (k)
eigenvalues with user specified features such as those of largest
real part or largest magnitude. Storage requirements are on the order
of n*k locations. No auxiliary storage is required. A set of Schur
basis vectors for the desired k-dimensional eigen-space is computed
which is numerically orthogonal to working precision. Numerically
accurate eigenvectors are available on request.
