DLA_SYRCOND estimates the Skeel condition number of  op(A) * op2(C)
    where op2 is determined by CMODE as follows
    CMODE =  1    op2(C) = C
    CMODE =  0    op2(C) = I
    CMODE = -1    op2(C) = inv(C)
    The Skeel condition number cond(A) = norminf( |inv(A)||A| )
    is computed by computing scaling factors R such that
    diag(R)*A*op2(C) is row equilibrated and computing the standard
    infinity-norm condition number.

          UPLO is CHARACTER*1
       = 'U':  Upper triangle of A is stored;
       = 'L':  Lower triangle of A is stored.

          N is INTEGER
     The number of linear equations, i.e., the order of the
     matrix A.  N >= 0.

          A is DOUBLE PRECISION array, dimension (LDA,N)
     On entry, the N-by-N matrix A.

          LDA is INTEGER
     The leading dimension of the array A.  LDA >= max(1,N).

          AF is DOUBLE PRECISION array, dimension (LDAF,N)
     The block diagonal matrix D and the multipliers used to
     obtain the factor U or L as computed by DSYTRF.

          LDAF is INTEGER
     The leading dimension of the array AF.  LDAF >= max(1,N).

          CMODE is INTEGER
     Determines op2(C) in the formula op(A) * op2(C) as follows:

     CMODE =  0    op2(C) = I
     CMODE = -1    op2(C) = inv(C)
