DSEVVE Matrix value input by ﬁnite element

Updated global Global communications array for this problem. This

array must be passed, untouched by the user, to

successive subroutines in this package.

Output ier Status response:

ier = 0 Normal return.

ier = −400 Incorrect processing path; DSEVOR

not called or eigenextraction already

begun.

ier = −401 Error in dynamic storage allocation.

ier = −402 Illegal value for either nnode or in

nodlst.

ier = −403 Illegal value for matrix designator.

ier = −404 At least one subscript pair

(nodlst(k),nodlst(l)) was not speciﬁed

in structure input. No room for value.

ier = −405 The B matrix was speciﬁed as

diagonal. Cannot add off-diagonal

nonzero value.

ier = −406 The B matrix was speciﬁed as an

identity matrix. Cannot add nonzero

value.

Notes Calls to DSEVV1, DSEVVC, DSEVVD, DSEVVE, and DSEVVM can be

intermixed. If the matrix entries are available as a sum of elemental matrices,

using DSEVVE is more efﬁcient than using DSEVV1.

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 matrix argument as ’addleft’.
