     This function checks if the input matrix is square and symmetric, then computes its eigenvalues using
     CuPy's sparse linear algebra solvers. It uses `eigsh` for more efficient computation.
-    IMPORTANT: it important to underline a couple of things regarding this function:
-    - installing using the command
-    .. code-block:: shell
-            python -m pip install cupy-cuda12x
-      does not allow, for some reason, to import cupyx.scipy.sparse.linalg, and it necessary to import the
-      function manually form the source code. The problem can be observed using python3.10, while for
-      python3.12 things seem to work.
-    - the eighs function in this case does not allow to compute *all* the eigenvalues, but only a number
+    Remark that the eigsh function in this case does not allow to compute *all* the eigenvalues, but only a number
     $m<n$, so here just a reduced portion is computed (starting form the ones which are greater in magnitude).
