[Lapack] CLAPACK


The two main LAPACK eigensolvers are DGEEV for the nonsymmetric matrices and 
DSYEV for symmetric/hermitian matrices. They are for dense matrices. So you can 
handle relatively small problem sizes.
For large sparse eigenvalue problems, you need to use other software packages. 
Please consult Jack website:

Hi LAPACK Engineers ,

I am very glad that I find your CLAPACK lib. on the website, but I don't know 
which subroutines can solve Eigen values of the large sparse matrix. Can you 
help me or give me the manual of it. Thanks.

Best,

-Jason
