+// The cuSolverDN library provides two different APIs; legacy and generic.
+// https://docs.nvidia.com/cuda/cusolver/index.html#naming-conventions
+// now only legacy APIs are used, while the general APIs have the potential to simplify code implementation.
+// for example, cucusolverDnXpotrf/getrf/geqrf/sytrf
+// More tests are needed to confirm that the generic APIs are operating normally, as they are not yet fully supported.
