[sage-support] Plots inside interact not working
Hi,
In the following code, nothing seems to show up when I put plot
inside interact, but it works when it's outside it.
def delta_l_hs(l, k, a):
return atan(spherical_bessel_J(l, k*a)/spherical_bessel_Y(l, k*a))
k = var('k')
#show(plot(delta_l_hs(5, k, 1), (k, -20, 20) ) )
@interact
def _(a=(1.0), k_min=(-20.0), k_max=(20.0), l=(0..50) ):
show(plot(delta_l_hs(l, k, a), (k, k_min, k_max) ) )
Help appreciated.

Okay, fair enough, but then why did it also do this later the same day when I used a copy of Sage I had kept around but not used in several months? It wasn't the first time I'd used that copy (something like 3.2.1) but it was the first time in a while; certainly I hadn't upgraded GAP. Does it just happen every time a different revision of GAP is used, up or down?

This is not a bug, is not odd, and is not an inefficiency. GAP get started to recreate it's startup cache whenever GAP is upgraded.

Use "show":
@interact
def _(r=(10.0), l_max=(0..20)):
show(parametric_plot3d( [x, y, z], (r_, 0, r), (theta, 0, 2*pi) ))

Thank you. I have downloaded, compiled and installed sage-3.4 from the
source tarball on my Kubuntu Intrepid PC. It has been packaged really
well because there were no hiccups. I only did two things after that.
1. On the first invocation of sage after installation, with
sudo sage
I ran
install_scripts('/usr/local/bin')
at the sage: prompt.
2. I also symlinked the sage script so:
sudo ln -sf /path-to-untarred-sage/sage-3.4/sage /usr/local/bin/sage
After that, things have been running smoothly and the problem with
solving non-linear equations that originally prompted this thread has gone.
>>> Does running "sage -maxima"
>>> run maxima? Can you solve simpler equations?
This time, on running sage -maxima I get:
---

For the benefit of the debian-sage team, the result for the Debian
package was

Perhaps the differences between these two versions, including the type
of Lisp, (plus other possible differences) contributed to the error I
originally saw with the Debian package.
Cheers!

[sage-support] interact not working with 3D plots
Hi,
The following code is not plotting for some reason. The silder comes
up and when I move it nothing happens.
def exp_ikz_expansion(r, theta, l_max):
s = 0
for l in range(l_max):
s = s + (2*l + 1)*I**l*spherical_bessel_J(l, r)*legendre_P(l,
cos(theta) )
return s
r_, theta = var('r_, theta')
x = r_*cos(theta)
y = r_*sin(theta)
z = exp_ikz_expansion(r_, theta, 10).real()
@interact
def _(r=(10.0), l_max=(0..20)):
parametric_plot3d( [x, y, z], (r_, 0, r), (theta, 0, 2*pi) )
Help appreciated.

As a shortcut, you could just use CC, which is the same as
ComplexField() (i.e., CC is ComplexField with the default 53 bits of
precision)
This would be analogous to the RR example below (except using complex
numbers instead of real numbers.
sage: CC is ComplexField()
True
sage: CC(sqrt(-1))
1.00*I
I'm surprised that this is orders of magnitude faster than using n(),
since I thought they were essentially doing the same thing. My timing
tests seem to indicate that the opposite is true:
sage: a=sqrt(2)
sage: timeit('CC(a)')
625 loops, best of 3: 33 µs per loop
sage: timeit('a.n()')
625 loops, best of 3: 19.2 µs per loop
sage: timeit('RR(a)')
625 loops, best of 3: 20.7 µs per loop
ah, but if the number is complex:
sage: a=sqrt(2)*I
sage: timeit('CC(a)')
625 loops, best of 3: 83.5 µs per loop
sage: timeit('a.n()')
625 loops, best of 3: 213 µs per loop
The code for n() first tries to convert to a real number, and if an
exception is raised, then it tries to convert to a complex number.
Maybe that try/except block is way, way too slow? Comments?
Thanks,
Jason
