DSLEFS One-call usage
ldrhs The leading dimension of array rhs as declared in the
calling program unit, with ldrhs ≥ neqns.
Updated rhs On input, rhs contains the nrhs right-hand sides. On
output, rhs has been overwritten with the computed
solutions.
Output rcond Estimate of the reciprocal of the 1-norm condition
number.
inrtia Array of length 3 containing, respectively, the number
of positive eigenvalues, the number of negative
eigenvalues, and an indicator if there are zero
eigenvalues.
global Global communications array for this problem. This
array must be passed, untouched by the user, to
successive subroutines in this package.
ier Status response:
ier = 0 Normal return.
ier = −101 Error in dynamic storage allocation
during matrix structure input.
ier = −102 neqns ≤ 0.
ier = −106 Unacceptable matrix structure.
ier = −201 Error in dynamic storage allocation
during ordering.
ier = −301 Error in dynamic storage allocation
during symbolic factorization.
ier = −302 Internal error.
ier = −401 Error in dynamic storage allocation
during value input.
ier = −501 Error in dynamic storage allocation
during factorization.
ier = −502 Error in dynamic storage allocation
during factorization.
ier = −503 Exactly zero pivot encountered during
factorization; matrix is singular.
ier = −602 nrhs ≤ 0.
ier = −603 ldrhs < neqns.
