.. _MATAR: MATAR ===== The **MATAR** sub-library is designed for dense and sparse data representations, and follows the data-oriented programming approach for highly efficient calculations. **MATAR** leverages **Kokkos** for performance portability over diverse architectures. The data representations developed in **MATAR** and the numerical tools in **ELEMENTS** are designed for performance, portability, and productivity (i.e., ease of use). **MATAR** is stored in a separate repository as it can aid many applications, as such, it is included as a GitHub submodule in the **ELEMENTS** repository. Please see the `MATAR documentation `_ for more details.
