# serred.f(3)

## NAME

TESTING/EIG/serred.f

## SYNOPSIS

### Functions/Subroutines

subroutine **serred** (path, nunit)\
 **SERRED**

## Function/Subroutine Documentation

### subroutine serred (character\*3 path, integer nunit)

**SERRED**

**Purpose:**

```
!>
!> SERRED tests the error exits for the eigenvalue driver routines for
!> REAL matrices:
!>
!> PATH  driver   description
!> ----  ------   -----------
!> SEV   SGEEV    find eigenvalues/eigenvectors for nonsymmetric A
!> SES   SGEES    find eigenvalues/Schur form for nonsymmetric A
!> SVX   SGEEVX   SGEEV + balancing and condition estimation
!> SSX   SGEESX   SGEES + balancing and condition estimation
!> SBD   SGESVD   compute SVD of an M-by-N matrix A
!>       SGESDD   compute SVD of an M-by-N matrix A (by divide and
!>                conquer)
!>       SGEJSV   compute SVD of an M-by-N matrix A where M >= N
!>       SGESVDX  compute SVD of an M-by-N matrix A(by bisection
!>                and inverse iteration)
!>       SGESVDQ  compute SVD of an M-by-N matrix A(with a
!>                QR-Preconditioned )
!>
```

**Parameters**

*PATH*

```
!>          PATH is CHARACTER*3
!>          The LAPACK path name for the routines to be tested.
!>
```

*NUNIT*

```
!>          NUNIT is INTEGER
!>          The unit number for output.
