Subject: eja: remove EJA tests from the operator spectral decomposition.
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=b0db25caf8a88f53e2845a4705cb96d6b836e401;p=sage.d.git

eja: remove EJA tests from the operator spectral decomposition.

The operator spectral decomposition is the usual linear algebra one,
so it doesn't make sense to test EJA results there.
