NAME

6       SLA_PORCOND  - SLA_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

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