[sage-support] Re: Possible Bug in Matrix Nullity Method
It is not a bug, but a consequence of a different convention. In Sage, nullity means left nullity, i.e. the dimension of the left kernel. In this example, m.nullity() + m.rank() = m.nrows(). For the more common right nullity (resp. kernel), use m.right_nullity() (resp. m.right_kernel()) instead. Indeed, in the example m.right_nullity() returns 2.

Surely not? For the left nullity the vectors are row vectors on the left, but the matrix is acting on the right (unless I got out of bed on the wrong side this norming).

I was also thinking of the fact that the kernel acts from the left via row operations on the matrix to its right. After re-reading it I see that it makes more sense if you read it right-associatively. (I could be somewhat left-right disoriented having just travelled from the UK to the continent.)

[sage-support] jmol on notebook blocked in firefox
Dear all, I am making a presentation of Sage for undergraduate math students next week, and when trying some old example I see that I cannot make a 3D graph interactive anymore. The first error is that the java plugin is "out of date and vulnerable". I've installed the latest plugin (from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html, namely Java Plug-in 1.7.0_25) and the problem persists. (I had tried open-jdk and icedtea in the past, and they seemed not to work well with sage/jmol, at least at the time). I'm running sage-6.1.1, on 64-bit up to date Debian Unstable (Linux), with Firefox 27 and Chromium 32. If I try to allow (by clicking on "run once"), I get a message "Your security setting have blocked an application from running with an out-of-date or expired version of Java." BTW, it works fine from the command line. But is there a way to run it from the notebook?

[sage-support] Best strategy for exporting/importing big lists or tuples to human-readable files?
Dear all, I kindly ask for your feedback on the following. My work involves the use of big lists that are of two kinds: a) lists of integers b) lists of lists of integers The contents of those lists come from quite long computations and I need to reuse those tuples often, so it is necessary to store those lists and retrieve them later, instead of recomputing all the elements everytime. It would also be great if they are stored in a way such that they are human-readable; the way I think of it, every element would be in another line, so that when I see them in my text editor, I can see the row number next to the element, and thus know the index of the element in the list. What do you recommend I should do for importing/exporting those lists to human-readable files? Any particular function or format (e.g. txt, csv, etc) that I should use? Any feedback would be greatly appreciated. George -- You received this message because you are subscribed to the Google Groups "sage-support" group.

[sage-support] Re: legends on plots
I have similar issues when running your code. However, the same code works
if you do not do implicit plotting:
var('x y')
xrange = (x,0,5)
yrange = (y,0,5)
f1 = plot(x**2,xrange,color='red',legend_label='x^2 - 4x + y^2 == 0')
f2 = plot(x,xrange,legend_label='x*y==1')
result = f1+f2
result.legend(True)
result.show(legend_loc='upper right',frame=True)
To me this implies that the problem is with implicit plotting.

Correct - I've been playing with this for the past few minutes, and contour
plots (of which implicit plots are a subset) simply don't do this, even
though there is code in the ContourPlot class to handle legends!
http://git.sagemath.org/sage.git/tree/src/sage/plot/contour_plot.py#n191
for implicit plot situation.
var('x y')
P = contour_plot(x^2+y^2==1,(x,-1,1),(y,-1,1),plot_points=150,
contours=(0,0), fill=False, cmap=["blue"],legend_label='test')
print P.legend()
P.legend(True)
print P.legend()
print P[0].options()['legend_label']
show(P)
shows this. Not only this, but the legend is inexplicably not set to True.
I have a feeling that we need to do what we do in plot/disk.py or
something; my guess (only a guess) is that the matplotlib thing that does
contour plots (contour) only accepts labels directly for the individual
contours, which
is http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.clabel
In
fact, http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.contour
seems to confirm that we shouldn't be trying to label contour plots with
legends. (Which makes sense, since they have their own labeling mechanism).
However, for implicit plots, this might cause a problem. A workaround
like at the bottom of
http://matplotlib.org/examples/pylab_examples/contourf_hatching.html
might work.

What could I do?
