NAME

/home/abuild/rpmbuild/BUILD/lapack-3.12.0/TESTING/LIN/zlaipd.f

SYNOPSIS

Functions/Subroutines


subroutine ZLAIPD (n, a, inda, vinda)
ZLAIPD

Function/Subroutine Documentation

subroutine ZLAIPD (integer n, complex*16, dimension( * ) a, integer inda, integer vinda)

ZLAIPD

Purpose:

!>
!> ZLAIPD sets the imaginary part of the diagonal elements of a complex
!> matrix A to a large value.  This is used to test LAPACK routines for
!> complex Hermitian matrices, which are not supposed to access or use
!> the imaginary parts of the diagonals.
!> 

Parameters

N

!>          N is INTEGER
!>         The number of diagonal elements of A.
!> 

A

!>          A is COMPLEX*16 array, dimension
!>                        (1+(N-1)*INDA+(N-2)*VINDA)
!>         On entry, the complex (Hermitian) matrix A.
!>         On exit, the imaginary parts of the diagonal elements are set
!>         to BIGNUM = EPS / SAFMIN, where EPS is the machine epsilon and
!>         SAFMIN is the safe minimum.
!> 

INDA

!>          INDA is INTEGER
!>         The increment between A(1) and the next diagonal element of A.
!>         Typical values are
!>         = LDA+1:  square matrices with leading dimension LDA
!>         = 2:  packed upper triangular matrix, starting at A(1,1)
!>         = N:  packed lower triangular matrix, starting at A(1,1)
!> 

VINDA

!>          VINDA is INTEGER
!>         The change in the diagonal increment between columns of A.
!>         Typical values are
!>         = 0:  no change, the row and column increments in A are fixed
!>         = 1:  packed upper triangular matrix
!>         = -1:  packed lower triangular matrix
