class
TensorLayout
¶ Parent class(es)
This class described the size and possibly the sparsity of a (sparse) tensor. It is used by the linear algebra backends to initialise tensors.
-
TensorLayout
(std::size_t primary_dim, Sparsity sparsity_pattern)¶ Create empty tensor layout
Create a tensor layout
Initialize tensor layout
-
