Key Switching in FIXEDMANUAL

Library Questions
1

In advance-real-numbers.cpp example code, when we use FIXEDMANUAL, the sequence is:

...
auto c2_depth2 = cc->EvalMult(c, c);
auto c2_depth1 = cc->Rescale(c2_depth2);
...

Does it mean the relinearization/key switching is done automatically? Is there a way to run it separately (Mult → Relinearization → Rescale)?

Yes, you can use the following:

ctMul = cc->EvalMultNoRelin(ct1, ct2);
cc->Relinearize(ctMul);
