ZLA_GERCOND_C computes the infinity norm condition number of


    op(A) * inv(diag(C)) where C is a DOUBLE PRECISION vector.

TRANS

          TRANS is CHARACTER*1


     Specifies the form of the system of equations:


       = 'N':  A * X = B     (No transpose)


       = 'T':  A**T * X = B  (Transpose)


       = 'C':  A**H * X = B  (Conjugate Transpose = Transpose)

N

          N is INTEGER


     The number of linear equations, i.e., the order of the


     matrix A.  N >= 0.

A

          A is COMPLEX*16 array, dimension (LDA,N)


     On entry, the N-by-N matrix A

LDA

          LDA is INTEGER


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

AF

          AF is COMPLEX*16 array, dimension (LDAF,N)


     The factors L and U from the factorization


     A = P*L*U as computed by ZGETRF.

LDAF

          LDAF is INTEGER


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

IPIV

          IPIV is INTEGER array, dimension (N)


     The pivot indices from the factorization A = P*L*U


     as computed by ZGETRF; row i of the matrix was interchanged


     with row IPIV(i).

C

          C is DOUBLE PRECISION array, dimension (N)


     The vector C in the formula op(A) * inv(diag(C)).

CAPPLY

          CAPPLY is LOGICAL


     If .TRUE. then access the vector C in the formula above.

INFO

          INFO is INTEGER


       = 0:  Successful exit.


     i > 0:  The ith argument is invalid.

WORK

          WORK is COMPLEX*16 array, dimension (2*N).


     Workspace.
