Note: the second dimension of the array
A
must be at least
max1,N.
On entry: details of the factorization of
A, as returned by
F07MRF (ZHETRF).
On exit: the factorization is overwritten by the
n by
n Hermitian matrix
A-1.
If UPLO='U', the upper triangle of A-1 is stored in the upper triangular part of the array.
If UPLO='L', the lower triangle of A-1 is stored in the lower triangular part of the array.
