********************************************************************
Introduction to the rocSOLVER API
********************************************************************
.. note::
The rocSOLVER library is in the early stages of active development. New features are being continuously added,
with new functionality documented at each `release of the ROCm platform <https://rocm.docs.amd.com/en/latest/release.html>`_.
Currently implemented functionality
====================================
The following tables summarize the functionality implemented for the different supported precisions in rocSOLVER's latest release.
All LAPACK and LAPACK-like main functions include *_batched* and *_strided_batched* versions. For a complete description of the listed
routines, please see the corresponding reference guides.
