## Synopsis

### Functions/Subroutines

subroutine **dget32** (rmax, lmax, ninfo, knt)**DGET32**

## Function/Subroutine Documentation

### subroutine dget32 (double precision rmax, integer lmax, integer ninfo, integer knt)

**DGET32**

**Purpose:**

DGET32 tests DLASY2, 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 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.
