NAME
       SRC/dlarmm.f

SYNOPSIS
   Functions/Subroutines
       double precision function dlarmm (anorm, bnorm, cnorm)
           DLARMM

Function/Subroutine Documentation
   double precision function dlarmm (double precision anorm, double precision
       bnorm, double precision cnorm)
       DLARMM

       Purpose:


            DLARMM returns a factor s in (0, 1] such that the linear updates

               (s * C) - A * (s * B)  and  (s * C) - (s * A) * B

            cannot overflow, where A, B, and C are matrices of conforming
            dimensions.

            This is an auxiliary routine so there is no argument checking.

       Parameters
           ANORM

                     ANORM is DOUBLE PRECISION
                     The infinity norm of A. ANORM >= 0.
                     The number of rows of the matrix A.  M >= 0.

           BNORM

                     BNORM is DOUBLE PRECISION
                     The infinity norm of B. BNORM >= 0.

           CNORM

                     CNORM is DOUBLE PRECISION
                     The infinity norm of C. CNORM >= 0.
