NAME

6       DLA_PORCOND  - DLA_PORCOND Estimate the Skeel condition number of op(A)
7       * op2(C)  where op2 is determined by CMODE as follows  CMODE = 1 op2(C)
8       = C  CMODE = 0 op2(C) = I  CMODE = -1 op2(C) = inv(C)  The Skeel condi‐
9       tion number cond(A) = norminf( |inv(A)||A| )  is computed by  computing
10       scaling  factors  R such that  diag(R)*A*op2(C) is row equilibrated and
11       computing the standard  infinity-norm condition number

PURPOSE

29          DLA_PORCOND Estimates the Skeel condition number of  op(A) * op2(C)
30          where op2 is determined by CMODE as follows
31          CMODE =  1    op2(C) = C
32          CMODE =  0    op2(C) = I
33          CMODE = -1    op2(C) = inv(C)
34          The Skeel condition number  cond(A) = norminf( |inv(A)||A| )
35          is computed by computing scaling factors R such that
36          diag(R)*A*op2(C) is row equilibrated and computing the standard
37          infinity-norm condition number.
