# aladhd.f(3)

## NAME

TESTING/LIN/aladhd.f

## SYNOPSIS

### Functions/Subroutines

subroutine **aladhd** (iounit, path)\
 **ALADHD**

## Function/Subroutine Documentation

### subroutine aladhd (integer iounit, character\*3 path)

**ALADHD**

**Purpose:**

```
!>
!> ALADHD prints header information for the driver routines test paths.
!>
```

**Parameters**

*IOUNIT*

```
!>          IOUNIT is INTEGER
!>          The unit number to which the header information should be
!>          printed.
!>
```

*PATH*

```
!>          PATH is CHARACTER*3
!>          The name of the path for which the header information is to
!>          be printed.  Current paths are
!>             _GE:  General matrices
!>             _GB:  General band
!>             _GT:  General Tridiagonal
!>             _PO:  Symmetric or Hermitian positive definite

!>             _SR:  Symmetric indefinite,
!>                     with rook (bounded Bunch-Kaufman) pivoting
!>             _SK:  Symmetric indefinite,
!>                     with rook (bounded Bunch-Kaufman) pivoting
!>                     ( new storage format for factors:
!>                       L and diagonal of D is stored in A,
!>                       subdiagonal of D is stored in E )
!>             _SP:  Symmetric indefinite packed,
!>                     with partial (Bunch-Kaufman) pivoting
!>             _HA:  (complex) Hermitian ,
!>                     Assen Algorithm
