Description

Provides an interface for common functions.

Syntax

interface = CommonFunctions()

Attributes

Methods

• inv_SVD
• egesz_resz
• atom_megkulonbozteto
• atom_tipus
• paritas

CommonFunctions::inv_SVD

Calculates the inverse of a badly conditioned matrix with SVD regularization.

Syntax

invA = interface.inv_SVD( A )

CommonFunctions::egesz_resz

Calculates the integer part of a real number.

Syntax

y = interface.egesz_resz( x )

CommonFunctions::atom_megkulonbozteto

Makes a difference between A and B type sites. (Can be used in hexagonal lattices.) --- Obsolete

Syntax

ret = interface.atom_megkulonbozteto( resz_index_mtx,index_koord )

CommonFunctions::atom_tipus

Makes a difference between A and B type sites. (Can be used in hexagonal lattices.) --- Obsolete

Syntax

ret = interface.atom_tipus( idx_i,idx_j )

CommonFunctions::paritas

Determine the parity of a number.

Syntax

p = interface.paritas( x )
