Parameters

storedTriangle  MatrixTriangle

            Specifies whether the details of the factorization are stored
            as an upper or lower triangular matrix.
            = 'U':  Upper triangular, form is A = U*D*UH;
            = 'L':  Lower triangular, form is A = L*D*LH.
            

n  Int32

            The order of the matrix A.  N >= 0.
            

a  Array2D<Complex<T>>

            A is complex array, dimension (LDA,N)
            The block diagonal matrix D and the multipliers used to
            obtain the factor U or L as computed by ZHETRF.
            

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

ipiv  Array1D<Int32>

            Dimension (N)
            Details of the interchanges and the block structure of D
            as determined by ZHETRF.
            

anorm  T

            The 1-norm of the original matrix A.
            

rcond  T

            The reciprocal of the condition number of the matrix A,
            computed as RCOND = 1/(ANORM * AINVNM), where AINVNM is an
            estimate of the 1-norm of inv(A) computed in this routine.
            

info  Int32

info is INTEGER
            = 0:  successful exit
            < 0:  if info = -i, the i-th argument had an illegal value
            

            An estimate is obtained for norm(inv(A)), and the reciprocal of the
            condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))).
