Detailed Description
Class MOIndexSpace describes a range of molecular orbitals or similar objects that are linear combinations of basis functions (e.g.
atomic orbitals). In general, such sets are subspaces of a full space of orbitals supported by the given basis. Orbitals can be symmetry-blocked, ordered by energy, etc. Examples of sets that can be described using MOIndexSpace are occupied MOs and virtual MOs.
Constructor & Destructor Documentation
◆ MOIndexSpace() [1/4]
| sc::MOIndexSpace::MOIndexSpace | ( | std::string | name, |
| const RefSCMatrix & | full_coefs, | ||
| const Ref< GaussianBasisSet > | basis, | ||
| const Ref< Integral > & | integral, | ||
| const vector< int > & | offsets, | ||
| const vector< int > & | nmopi, | ||
| IndexOrder | moorder = symmetry, |
||
| const RefDiagSCMatrix & | evals = 0 |
||
| ) |
This function constructs an MOIndexSpace from (blocked) space full_coefs.
Block i will contain vectors [ offsets[i], offsets[i]+nmopi[i]-1 ] . By default, the space maintains the same blocked structure and the same order within blocks as the original space (moorder=symmetry). If moorder=energy and eigenvalues evals are provided, then all vectors will be put in one block and sorted according to ascending evals.
- Parameters
-
name – the name of this MOIndexSpace full_coefs – symmetry-blocked transformation coefficient matrix (AO by MO) for the full space basis – basis set integral – integral factory offsets – block offsets nmopi – new block sizes moorder – specifies new ordering of vectors evals – used to sort the vectors
◆ MOIndexSpace() [2/4]
| sc::MOIndexSpace::MOIndexSpace | ( | std::string | name, |
| const RefSCMatrix & | full_coefs, | ||
| const Ref< GaussianBasisSet > | basis, | ||
| const Ref< Integral > & | integral, | ||
| const RefDiagSCMatrix & | evals, | ||
| int | nfzc, | ||
| int | nfzv, | ||
| IndexOrder | moorder = energy |

| ) |
This constructor should be used when the MOIndexSpace object is a subspace of a full orbital space.
Similarly to the previous constructor, it constructs an MOIndexSpace object using a symmetry-blocked transformation coefficient matrix (AO by MO) for the full space, basis set, "eigenvalues" and the number of orbitals with lowest (nfzc) and highest (nfzv) eigenvalues to be dropped. The orbitals in the constructed space are ordered by energy.
◆ MOIndexSpace() [3/4]
| sc::MOIndexSpace::MOIndexSpace | ( | std::string | name, |
| const RefSCMatrix & | full_coefs, | ||
| const Ref< GaussianBasisSet > | basis, | ||
| const Ref< Integral > & | integral | ||
| ) |
This constructor should be used when the MOIndexSpace object is the full orbital space.
The orbitals will be symmetry-blocked.
◆ MOIndexSpace() [4/4]
| sc::MOIndexSpace::MOIndexSpace | ( | std::string | name, |
| const Ref< MOIndexSpace > & | orig_space, | ||
| const RefSCMatrix & | new_coefs, | ||
| const Ref< GaussianBasisSet > & | new_basis | ||
| ) |
This constructor is a true hack introduced because I have no idea how to construct what I need.
It will copy orig_space but replace it's coefs with new_coefs, and its basis with new_basis.
Member Function Documentation
◆ save_data_state()

virtual |
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.
This must be implemented by the derived class if the class has data.
Reimplemented from sc::SavableState.
