CLA_PORCOND_X computes the infinity norm condition number of op(A)*diag(x) for Hermitian positive-definite matrices.
CLA_PORCOND_X Computes the infinity norm condition number of op(A) * diag(X) where X is a COMPLEX vector.
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 COMPLEX 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 COMPLEX array, dimension (LDAF,N) The triangular factor U or L from the Cholesky factorization A = U**H*U or A = L*L**H, as computed by CPOTRF.
LDAF is INTEGER The leading dimension of the array AF. LDAF >= max(1,N).
X is COMPLEX array, dimension (N) The vector X in the formula op(A) * diag(X).
INFO is INTEGER = 0: Successful exit. i > 0: The ith argument is invalid.
WORK is COMPLEX array, dimension (2*N). Workspace.
