Detailed Description

template<EvaluatorVariant variant, int dim, typename Number, typename Number2>
struct internal::EvaluatorTensorProduct< variant, dim, 0, 0, Number, Number2 >

Internal evaluator for shape function using the tensor product form of the basis functions. The same as the other templated class but without making use of template arguments and variable loop bounds instead.

Template Parameters
dimSpace dimension in which this class is applied
NumberAbstract number type for input and output arrays
Number2Abstract number type for coefficient arrays (defaults to same type as the input/output arrays); must implement operator* with Number and produce Number as an output to be a valid type

Constructor & Destructor Documentation

◆ EvaluatorTensorProduct() [1/3]

template<EvaluatorVariant variant, int dim, typename Number , typename Number2 >
internal::EvaluatorTensorProduct< variant, dim, 0, 0, Number, Number2 >::EvaluatorTensorProduct ( )
inline

Empty constructor. Does nothing. Be careful when using 'values' and related methods because they need to be filled with the other constructor

Definition at line 1634 of file tensor_product_kernels.h.

◆ EvaluatorTensorProduct() [2/3]

template<EvaluatorVariant variant, int dim, typename Number , typename Number2 >
internal::EvaluatorTensorProduct< variant, dim, 0, 0, Number, Number2 >::EvaluatorTensorProduct ( const AlignedVector< Number2 > &  shape_values,
const AlignedVector< Number2 > &  shape_gradients,
const AlignedVector< Number2 > &  shape_hessians,
const unsigned int  n_rows = 0,
const unsigned int  n_columns = 0 
)
inline

Constructor, taking the data from ShapeInfo
