## Detailed Description

### template<int dim, int n_rows, int n_columns, typename Number, typename Number2> struct internal::EvaluatorTensorProduct< evaluate_symmetric, dim, n_rows, n_columns, Number, Number2 >

Internal evaluator for 1d-3d shape function using the tensor product form of the basis functions. This class specializes the general application of tensor-product based elements for "symmetric" finite elements, i.e., when the shape functions are symmetric about 0.5 and the quadrature points are, too.

Template Parameters
 dim Space dimension in which this class is applied n_rows Number of rows in the transformation matrix, which corresponds to the number of 1d shape functions in the usual tensor contraction setting n_columns Number of columns in the transformation matrix, which corresponds to the number of 1d shape functions in the usual tensor contraction setting Number Abstract number type for input and output arrays Number2 Abstract 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
