Detailed Description
Rountines for symmetric tridiagonal eigenvalue problems (for all eigenvalues and optionally all eigenvectors of a symmetric tridiagonal matrix).
The LAPACK routine xSTEV (i.e. dstev_() if Real is double, or sstev_() if Real is float) is required. The solvers declared here are indeed wrappers.
