subroutine zerrst ( character*3  PATH,
integer  NUNIT 
)

ZERRST

Purpose: 
 ZERRST tests the error exits for ZHETRD, ZUNGTR, CUNMTR, ZHPTRD,

 ZHEEV, CHEEVX, CHEEVD, ZHBEV, CHBEVX, CHBEVD,
 ZHPEV, CHPEVX, CHPEVD, and ZSTEDC.
Parameters
[in]PATH
          PATH is CHARACTER*3
          The LAPACK path name for the routines to be tested.
[in]NUNIT
          NUNIT is INTEGER
          The unit number for output.
