# sget32.f(3)

## NAME

TESTING/EIG/sget32.f

## SYNOPSIS

### Functions/Subroutines

subroutine **sget32** (rmax, lmax, ninfo, knt)\
 **SGET32**

## Function/Subroutine Documentation

### subroutine sget32 (real rmax, integer lmax, integer ninfo, integer knt)

**SGET32**

**Purpose:**

```
!>
!> SGET32 tests SLASY2, a routine for solving
!>
!>         op(TL)*X + ISGN*X*op(TR) = SCALE*B
!>
!> where TL is N1 by N1, TR is N2 by N2, and N1,N2 =1 or 2 only.
!> X and B are N1 by N2, op() is an optional transpose, an
!> ISGN = 1 or -1. SCALE is chosen less than or equal to 1 to
!> avoid overflow in X.
!>
!> The test condition is that the scaled residual
!>
!> norm( op(TL)*X + ISGN*X*op(TR) = SCALE*B )
!>      / ( max( ulp*norm(TL), ulp*norm(TR)) * norm(X), SMLNUM )
!>
!> should be on the order of 1. Here, ulp is the machine precision.
!> Also, it is verified that SCALE is less than or equal to 1, and
!> that XNORM = infinity-norm(X).
!>
```

**Parameters**

*RMAX*

```
!>          RMAX is REAL
!>          Value of the largest test ratio.
!>
```

*LMAX*

```
!>          LMAX is INTEGER
!>          Example number where largest test ratio achieved.
!>
```

*NINFO*

```
!>          NINFO is INTEGER
!>          Number of examples returned with INFO.NE.0.
!>
```

*KNT*

```
!>          KNT is INTEGER
!>          Total number of examples tested.
