* Purpose
* =======
*
-* SLA_GBRPVGRW computes the reciprocal pivot growth factor
-* norm(A)/norm(U). The "max absolute element" norm is used. If this is
-* much less than 1, the stability of the LU factorization of the
-* (equilibrated) matrix A could be poor. This also means that the
-* solution X, estimated condition numbers, and error bounds could be
-* unreliable.
