| Pscf::Pspc::BFieldComparison::BFieldComparison | ( | int | begin = 0 | ) |
Constructor.
The basis function with index 0 in a symmetry adapted basis is always a spatially homogeneous function, i.e., a constant. In some situations, we may be interested in determining whether two fields are equivalent to within a constant.
Set begin = 0 to include the coefficient of the first basis function in the comparison, thus determining how close to fields are to being strictly equal.
Set begin = 1 to exclude the coefficient of the first basis function, thus comparing only deviatoric parts of the fields.
- Parameters
-
begin index of first element to include in comparison.
