* Scaled epsilon the wrong way.Gravatar Antonio Sanchez2021-04-07
| | | | | | Should have been 0.5 to widen the bounds, since this is inverse precision. Setting to 0.5, however, leads to many more failing tests at Google, so reverting to 1 for now.
* Fix SelfAdjoingEigenSolver (#2191)Gravatar Antonio Sanchez2021-04-05
| | | | | | | | | | | | | | Adjust the relaxation step to use the condition ``` abs(subdiag[i]) <= epsilon * sqrt(abs(diag[i]) + abs(diag[i+1])) ``` for setting the subdiagonal entry to zero. Also adjust Wilkinson shift for small `e = subdiag[end-1]` - I couldn't find a reference for the original, and it was not consistent with the Wilkinson definition. Fixes #2191.

* applying EIGEN_DECLARE_TEST to *gpu* testsGravatar Deven Desai2018-07-17
| | | | | | | | | | | | | Also, a few minor fixes for GPU tests running in HIP mode. 1. Adding an include for hip/hip_runtime.h in the Macros.h file For HIP __host__ and __device__ are macros which are defined in hip headers. Their definitions need to be included before their use in the file. 2. Fixing the compile failure in TensorContractionGpu introduced by the commit to "Fuse computations into the Tensor contractions using output kernel" 3. Fixing a HIP/clang specific compile error by making the struct-member assignment explicit
