Header: ``<pressio/ops.hpp>``

API

.. code-block:: cpp

  namespace pressio { namespace ops{

  template <class T1, class T2>
  void elementwise_reciprocal(const T1 & z, T2 & y);

  }} // end namespace pressio::ops

Description
-----------

* Computes the elementwise reciprocal of ``z`` and stores it in ``y`` (``y = 1/z``)

* ``T1`` and ``T2`` must be one-dimensional containers with compatible scalar types. They may be:

  * Eigen vectors or Pressio rank-1 expressions built from Eigen containers

  * Kokkos rank-1 views or Pressio rank-1 expressions built from Kokkos containers

  * Tpetra vectors or column expressions

  * Tpetra block vectors or column expressions
