Oops, sorry.
> I got the plotting problem before too, see comment 17. It's something in
the `fast_callable` implementation if I recall correctly, but I couldn't
figure out how to fix it at the time.
`exp_integral_e()` is a `BuiltinFunction` too, and needs two parameters
but
{{{
sage: f=fast_callable(exp_integral_e(x,1),domain=CDF,expect_one_var=True)
sage: f(8)
0.0452114820619
sage: f=fast_callable(hypergeometric([x], [], y),domain=CDF,vars=[x,y])
sage: f(8,9)
5.96046447754e-08
sage: f=fast_callable(hypergeometric([x], [], 2),domain=CDF,vars=[x])
sage: f(8)
1.0
}}}
so I changed
{{{
f = fast_callable(f, domain=CDF, expect_one_var=TRUE)
}}}
to
{{{
f = fast_callable(f, domain=CDF, vars=[x])
}}}
in `complex_plot()`. Now the one var case works but not the two etc. So it
seems the handling of `expect_one_var` in `fast_callable()` is wrong, as I
already said.
