Description (last modified by rbeezer)

As the summary says, this patch improves eigenvalues of matrices with double-precision floating-point entries.

  1. Uses SciPy's eigh routine for symmetric and Hermitian matrices.
  2. Allows grouping of "equal" eigenvalues, based on a tolerance parameter.

Apply:

  1. trac_11608-eigenvalues-symmetric-multiplicity-rebase.patch
