Detailed Description

SumIntCoor is used to construct linear combinations of internal coordinates.

The following is a sample ParsedKeyVal input for a SumIntCoor object:

  sumintcoor<SumIntCoor>: (
    coor: [
      <StreSimpleCo>:( atoms = [ 1 2 ] )
      <StreSimpleCo>:( atoms = [ 2 3 ] )
      ]
    coef = [ 1.0 1.0 ]
    )

Constructor & Destructor Documentation

SumIntCoor::SumIntCoor ( const Ref< KeyVal > & )

The KeyVal constructor. coor A vector of IntCoor objects that define the summed coordinates. coef A vector of floating point numbers that gives the coefficients of the summed coordinates.

Member Function Documentation

void SumIntCoor::add ( Ref< IntCoor > &, double coef )

Add a coordinate to the linear combination. coef is the coefficient for the added coordinate.

void SumIntCoor::save_data_state ( StateOut & s ) [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 IntCoor.
