ffsim.init_cache

ffsim.init_cache(norb, nelec)

Initialize cached objects.

Call this function to prepare ffsim for performing operations with given values of norb and nelec. Typically there is no need to call this function, but it should be called before benchmarking to avoid counting the cost of initializing cached lookup tables.

Parameters:

• norb (int) – The number of spatial orbitals.

• nelec (tuple[int, int]) – The number of alpha and beta electrons.

Return type:

None
