ier = ±741 Error in deallocation of storage for
second set of Lanczos recurrence
vectors.
warnng Warning status. warnng includes several different
warnings encoded in a three-digit decimal integer:
low-order digit:
warnng = xx0 Normal return.
warnng = xx1 Fewer modes computed than
requested (interval does not include
requested number).
warnng = xx2 Fewer modes computed than
requested because eigenvalues are
different in size.
warnng = xx3 Both of the above conditions occurred.
ten’s digit:
warnng = x0x Normal return.
warnng = x1x At some point in the process, an
inconsistent inertia count was found.
hundred’s digit:
warnng = 0xx Normal return.
warnng = 1xx Interval had to be expanded because
one or both endpoints were very close
to eigenvalues.
Notes Actual character arguments in a subroutine call may be longer than
corresponding dummy arguments. Therefore, readability of the CALL
statement may be improved by coding the pbtype argument as ’vibration’ or
’buckling’.
