CLA_SYRCOND_C Computes the infinity norm condition number of


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

UPLO

          UPLO is CHARACTER*1


       = 'U':  Upper triangle of A is stored;


       = 'L':  Lower triangle of A is stored.

N

          N is INTEGER


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


     matrix A.  N >= 0.

A

          A is COMPLEX 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 array, dimension (LDAF,N)


     The block diagonal matrix D and the multipliers used to


     obtain the factor U or L as computed by CSYTRF.

LDAF

          LDAF is INTEGER


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

IPIV

          IPIV is INTEGER array, dimension (N)


     Details of the interchanges and the block structure of D


     as determined by CSYTRF.

C

          C is REAL 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 array, dimension (2*N).


     Workspace.
