## Synopsis

### Functions/Subroutines

subroutine **dget33** (rmax, lmax, ninfo, knt)**DGET33**

## Function/Subroutine Documentation

### subroutine dget33 (double precision rmax, integer lmax, integer ninfo, integer knt)

**DGET33**

**Purpose:**

DGET33 tests DLANV2, a routine for putting 2 by 2 blocks into standard form. In other words, it computes a two by two rotation [[C,S];[-S,C]] where in [ C S ][T(1,1) T(1,2)][ C -S ] = [ T11 T12 ] [-S C ][T(2,1) T(2,2)][ S C ] [ T21 T22 ] either 1) T21=0 (real eigenvalues), or 2) T11=T22 and T21*T12<0 (complex conjugate eigenvalues). We also verify that the residual is small.

**Parameters***RMAX*RMAX is DOUBLE PRECISION 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.
