Hi,
I need to find the 2nd smallest eigenvalue and corresponding eigenvector of a large sparse real symmetric matrix. The matrix is stored in CSR format. I see that SSYEVX function does the required work, but the zeros entries in the matrix also has to be stored. Is there any other function which does my work..? or any other suggestions please.
Regards,
Kiran.

Hi Gennady,
Not for CSR format but are there any functions to find the second smallest eigenvector of a sparse symmetric real matrix stored in any format.
