REAL FUNCTION SGET06( RCOND, RCONDC )
*
* -- LAPACK test routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* Courant Institute, Argonne National Lab, and Rice University
* September 30, 1994
*
* .. Scalar Arguments ..
REAL RCOND, RCONDC
* ..
*
* Purpose
* =======
*
* SGET06 computes a test ratio to compare two values for RCOND.
*
* Arguments

*
* RCOND (input) REAL
* The estimate of the reciprocal of the condition number of A,
* as computed by SGECON.
*
* RCONDC (input) REAL
* The reciprocal of the condition number of A, computed as
* ( 1/norm(A) ) / norm(inv(A)).
*
* =====================================================================
*
* .. Parameters ..
