Detailed Description

template<typename scalar_t, typename scalar_ops = ScalarOps<scalar_t>>
class mfem::InvariantsEvaluator2D< scalar_t, scalar_ops >

Auxiliary class for evaluating the 2x2 matrix invariants and their first and second derivatives.

The type scalar_t must support the standard operations: 

=, +=, -=, +, -, *, /, unary -, int*scalar_t, int/scalar_t, scalar_t/int

The type scalar_ops must define the static method: 

scalar_t sign(const scalar_t &);
