Detailed Description

Determine eigenvalues for small symmetric, tridiagonal matrix.

Utility / shared functionality for bisection kernels.

Implementation based on the sample provided with the CUDA 6.0 SDK, for which the creation of derivative works is allowed by including the following statement: "This software contains source code provided by NVIDIA Corporation."
