ier = ±703 Illegal specification for pbtype.
ier = ±704 Illegal specification for which.
ier = ±705 which = highest for an interval that
spans zero.
ier = ±706 Insufficient dynamic memory for
factorization.
ier = ±707 Internal error during factorization.
ier = ±710 Factorization save error in finite
interval analysis.
ier = ±720 Error in storage allocation for first set
of Lanczos recurrence vectors.
ier = ±721 Error in storage allocation for second
set of Lanczos recurrence vectors.
ier = ±722 Error in storage allocation for
eigenvectors.
ier = ±723 Insufficient storage during Lanczos
iteration.
ier = ±724 QL iteration did not converge.
ier = ±725 Number of eigenvalues computed
exceeded storage limitations.
ier = ±726 Internal error involving access of
Lanczos recurrence vectors.
ier = ±727 Singular Value Decomposition did not
converge.
ier = ±728 Gram-Schmidt reorthogonalization
did not converge.
ier = ±729 Three numeric factorizations in a row
failed. Probable cause is that this is
not a symmetric generalized
eigenproblem.

exceeded storage limitations.
ier = ±731 Error during restoration of a numeric
factorization.
ier = ±740 Error in deallocation of storage for
first set of Lanczos recurrence vectors.
