* Arguments
* =========
*
-* UPLO (input) CHARACTER*1
-* Specifies whether the details of the factorization are stored
-* as an upper or lower triangular matrix.
-* = 'U': Upper triangular, form is A = U*D*U**H;
-* = 'L': Lower triangular, form is A = L*D*L**H.
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0.
-*
-* A (input/output) COMPLEX array, dimension (LDA,N)
-* On entry, the NNB diagonal matrix D and the multipliers
-* used to obtain the factor U or L as computed by CHETRF.
+*> \param[in] UPLO
+*> \verbatim
+*> UPLO is CHARACTER*1
+*> Specifies whether the details of the factorization are stored
+*> as an upper or lower triangular matrix.
+*> = 'U': Upper triangular, form is A = U*D*U**H;
+*> = 'L': Lower triangular, form is A = L*D*L**H.
+*> \endverbatim
+*>
+*> \param[in] N
+*> \verbatim
+*> N is INTEGER
+*> The order of the matrix A. N >= 0.
+*> \endverbatim
+*>
+*> \param[in,out] A
+*> \verbatim
+*> A is COMPLEX array, dimension (LDA,N)
+*> On entry, the NNB diagonal matrix D and the multipliers
+*> used to obtain the factor U or L as computed by CHETRF.
+*> \endverbatim
+*> \verbatim
+*> On exit, if INFO = 0, the (symmetric) 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.
+*> \endverbatim
+*>
+*> \param[in] LDA
+*> \verbatim
+*> LDA is INTEGER
+*> The leading dimension of the array A. LDA >= max(1,N).
+*> \endverbatim
+*>
+*> \param[in] IPIV
+*> \verbatim
+*> IPIV is INTEGER array, dimension (N)
+*> Details of the interchanges and the NNB structure of D
+*> as determined by CHETRF.
+*> \endverbatim
+*>
+*> \param[out] WORK
+*> \verbatim
+*> WORK is COMPLEX array, dimension (N+NNB+1,NNB+3)
