Detailed Description

template<class ExecutionSpace>
class Stokhos::SymmetricDiagonalSpec< ExecutionSpace >

Symmetric diagonal storage for a dense matrix.

Block storage size = dimension * ( dimension + 1 ) / 2

Given block_dim then total_diagonal_count = 1 + dimension / 2

If dimension is even then the last diagonal is only half length.
