CLAIPD 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.
N
N is INTEGER
The number of diagonal elements of A.
A
A is COMPLEX 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
