Detailed Description

template<bool nonSingular, bool semiPositive, bool semiNegative, std::ptrdiff_t offset = 0>
struct Dune::ACFem::Expressions::ExpressionSign< nonSingular, semiPositive, semiNegative, offset >

A class mainting the sign of an expression during operations.

Parameters
[in]nonSingularFor scalar means non-zero, for operators invertible. The boundary-value models use this to indicate that the resulting system will be solvable (if applicable).
[in]semiPositiveFor scalars means >= 0, for operators positive semi-definite.
[in]semiNegativeFor scalars means <= 0, for operators negative semi-definite.
[in]offsetOptional integral value defines the "zero point". Defaults to 0.
