-*
-* X (input) COMPLEX array, dimension at least
-* ( 1 + ( N - 1 )*abs( INCX ) ).
-* Before entry, the incremented array X must contain the N-
-* element vector x.
-* Unchanged on exit.
-*
-* INCX (input) INTEGER
-* On entry, INCX specifies the increment for the elements of
-* X. INCX must not be zero.
-* Unchanged on exit.
-*
-* A (input/output) COMPLEX array, dimension ( LDA, N )
-* Before entry, with UPLO = 'U' or 'u', the leading n by n
-* upper triangular part of the array A must contain the upper
-* triangular part of the symmetric matrix and the strictly
-* lower triangular part of A is not referenced. On exit, the
-* upper triangular part of the array A is overwritten by the
-* upper triangular part of the updated matrix.
-* Before entry, with UPLO = 'L' or 'l', the leading n by n
-* lower triangular part of the array A must contain the lower

-* LDA (input) INTEGER
-* On entry, LDA specifies the first dimension of A as declared
