[Lapack] About fortran program

Dear Gulay,

The EISPACK routine cg is a very well tried and tested routine, so it is 
almost certain that you are calling it incorrectly.  Note that you have 
to supply the matrix A as two separate real (double precision) arrays, 
one for the real parts, the second for the imaginary parts.

The modern equivalent of EISPACK is LAPACK see:

Routine DGEEV is the LAPACK equivalent of cg.

Best wishes,

Sven Hammarling.
