CLAIPD

## Function/Subroutine Documentation

### subroutine claipd (integer n, complex, dimension( * ) a, integer inda, integer vinda)

CLAIPD

Purpose:

``` 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.```
Parameters

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```
