-* Purpose
-* =======
-*
-* ZPPTRF computes the Cholesky factorization of a complex Hermitian
-* positive definite matrix A stored in packed format.
-*
-* The factorization has the form
-* A = U**H * U, if UPLO = 'U', or
-* A = L * L**H, if UPLO = 'L',
-* where U is an upper triangular matrix and L is lower triangular.
-*
-* Arguments
-* =========
-*
-* UPLO (input) CHARACTER*1
-* = 'U': Upper triangle of A is stored;
-* = 'L': Lower triangle of A is stored.
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0.
-*
-* AP (input/output) COMPLEX*16 array, dimension (N*(N+1)/2)
-* On entry, the upper or lower triangle of the Hermitian matrix
-* A, packed columnwise in a linear array. The j-th column of A
-* is stored in the array AP as follows:
-* if UPLO = 'U', AP(i + (j-1)*j/2) = A(i,j) for 1<=i<=j;
-* if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = A(i,j) for j<=i<=n.
-* See below for further details.
-*
-* On exit, if INFO = 0, the triangular factor U or L from the
-* Cholesky factorization A = U**H*U or A = L*L**H, in the same
-* storage format as A.
-*
-* INFO (output) INTEGER
-* = 0: successful exit
-* < 0: if INFO = -i, the i-th argument had an illegal value
-* > 0: if INFO = i, the leading minor of order i is not
-* positive definite, and the factorization could not be
-* completed.
-*
-* Further Details
-* ===============
-*
-* The packed storage scheme is illustrated by the following example
-* when N = 4, UPLO = 'U':
-*
-* Two-dimensional storage of the Hermitian matrix A:
-*
-* a11 a12 a13 a14
-* a22 a23 a24
-* a33 a34 (aij = conjg(aji))
-* a44
-*
-* Packed storage of the upper triangle of A:
-*
-* AP = [ a11, a12, a22, a13, a23, a33, a14, a24, a34, a44 ]
