inline |
Creates and returns a view that matches the provided view in Kokkos Layout.
[in] | view | - the view to match |
[in] | label | - a string label for the view to be created |
[in] | dims | - dimensions to use for the view (the logical dimensions; this method handles adding the derivative dimension required for Fad types). |
This method is particularly useful because we use LayoutStride as the Kokkos Layout in a number of places, and LayoutStride views cannot be instantiated without also providing stride information.
