Detailed Description
The SetIntCoor class describes a set of internal coordinates.
It can automatically generate these coordinates using a integral coordinate generator object (see the IntCoorGen class) or the internal coordinates can be explicity given.
The following is a sample ParsedKeyVal input for a SetIntCoor object.
setintcoor<SetIntCoor>: [
<SumIntCoor>: (
coor: [
<StreSimpleCo>:( atoms = [ 1 2 ] )
<StreSimpleCo>:( atoms = [ 2 3 ] )
]
coef = [ 1.0 1.0 ]
)
<BendSimpleCo>:( atoms = [ 1 2 3 ] )
]Constructor & Destructor Documentation
sc::SetIntCoor::SetIntCoor (const Ref< KeyVal > &)
The KeyVal constructor.
- generator
A IntCoorGen object that will be used to generate the internal coordinates.
- i
A sequence of integer keywords, all $i$ for $0 leq i < n$, can be assigned to IntCoor objects.
Member Function Documentation
virtual void sc::SetIntCoor::guess_hessian (Ref< Molecule > &, RefSymmSCMatrix &) [virtual]
Create an approximate Hessian for this set of coordinates. This Hessian is a symmetric matrix whose i'th diagonal is the force constant for the i'th coordinate in the set.
void sc::SetIntCoor::save_data_state (StateOut &) [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.
