Parameters

storedTriangle  MatrixTriangle

 

n  Int32

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

a  Span<Complex<Double>>

            A is TComplex array, dimension (LDA,N)
            On entry, the block diagonal matrix D and the multipliers
            used to obtain the factor U or L as computed by ZHETRF.
            On exit, if INFO = 0, the (Hermitian) inverse of the original
            matrix.  If UPLO = 'U', the upper triangular part of the
            inverse is formed and the part of A below the diagonal is not
            referenced; if UPLO = 'L' the lower triangular part of the
            inverse is formed and the part of A above the diagonal is
            not referenced.
            

lda  Int32

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

ipiv  ReadOnlySpan<Int32>

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

info  Int32

            = 0: successful exit
            < 0: if INFO = -i, the i-th argument had an illegal value
            > 0: if INFO = i, D(i,i) = 0; the matrix is singular and its
                 inverse could not be computed.
