Changes (by zimmerma):
* status: needs_review => needs_work
* work_issues: rebase to 5.0.beta10 => define expintegral_ei
Comment:
while looking in the sources for the old name {{{expintegral_e}}} I found
the following
instance:
{{{
sage: search_src("expintegral_e")
functions/exp_integral.py:393: x*log_integral(x) -
expintegral_ei(2*log(x))
sage: expintegral_ei?
Object `expintegral_ei` not found.
}}}
That should be fixed too.
Paul
PS: the patch applied cleanly to 5.0, thus I removed the "rebase to
5.0.beta10" work issue
