-*  ZSYTRI2 computes the inverse of a complex symmetric indefinite matrix
+*  ZSYTRI2 computes the inverse of a COMPLEX*16 hermitian indefinite matrix
 *  A using the factorization A = U*D*U**T or A = L*D*L**T computed by
 *  ZSYTRF. ZSYTRI2 sets the LEADING DIMENSION of the workspace
 *  before calling ZSYTRI2X that actually computes the inverse.
