Hello everybody !!!
I almost never use the sloane_find function, but it seems to be in a
very bad mood :
sage: sloane_find([1,1,2,3,5,8,13,21])
Searching Sloane's online database...

Perhaps it is just tired of saying it's Fibonacci's sequence and you
should know it each time it is fed with
Hi,
as a newbie I want to check some relations between Bessel functions
and Zernike polynomials.
To get some ideas first I tried to plot Bessel functions of different
type as indicated in the Bessel?.
To be able to distinguish the different types one wants to use color,
but something like
g =
You're implying that 4.7.1 or 4.7.2 fix this issue in some way? I
don't see anything in the release notes which would cause me to
suspect that.

Unless I'm still too caffeine-deprived, I think the issue is that you are one
of the first to try

Yes, I think that's right, Justin.
I just tried this:
1. Build libpng and libjpeg, static-only, and install to SAGE_LOCAL/
lib/.
2. Build Imaging-1.1.7 (after setting CPPFLAGS and LDFLAGS to point
to SAGE_LOCAL), and install to SAGE_LOCAL/lib.
3. Remove my /opt/local/lib/ directory.
Now
sage: pl=sum([plot(lambda x:bessel_J(x,n),(x,0,1),color=hue(n/
5.0),legend_label=str(n)) for n in [1..4]])
sage: pl.show()
sage: numerical_integral(lambda x:bessel_J(x,2),1,2)

I installed PIL 1.1.7 (which has been out for a while) into my Sage.
Still broken:
Image.fromarray(scipy.lena()).show()
I think PIL just can't imagine a grayscale int32 image. When I do
this instead
Image.fromarray(numpy.asarray(scipy.lena(),
dtype=numpy.uint8)).show()
it works.
On Nov
sage: maxima('integrate(bessel_j(1,x), x)')
-bessel_j(0,x)

What's the objection to linking PIL statically against libjpeg? It
would remove a lot of uncertainty in the build. PIL seems to be the
only place libjpeg is used.

My suggestion doesn't require binary build machines to have libjpeg
installed. In fact, you don't want it installed. And there seems to
be no technical reason to not statically link PIL against libjpeg.a.
But there *is* a reason to not *dynamically* link against
libjpeg.dylib, libpng.dylib, or

Ah, I see. Yes, libjpeg is built from source on the build machines,
but only temporarily. It could be installed in /tmp, for instance,
and removed as part of the build process, after PIL is built, for
instance. I just used SAGE_LOCAL without thinking too hard about it.
I'm not familiar yet

Is there any particular reason this isn't part of sage.el already?

I'm using sage for data analysis and number crunching in my physical
chemistry class and stumbled on a curiosity while replacing the
variables that are used by find_fit:
When replacing variables like 'a, b ,c' for 'c1, c2, c3' on a 11th
degree polynomial the whole find_fit-function goes nuts and
