Dear list,
if I do a
plot([1,2],[1,2])
plot([1,2],[1,3])
plot([1,2],[1,4])
I will get three lines. All have linestyle='-', the colour is changed
automatically: blue, green, red, ...
Can I change this behaviour to: All have the colour black, and the
linestyle is changed /automatically/ '-', '--'

do you have scipy installed? i.e. does

work? if so, what is

if scipy is not installed, i think you need to install it in order to

hey pau,
ellipk is in scipy.special:

Phase = 4.*sqrt(p/(p -6. - 2.*e)) * ellipk(-4.*e/(p - 6. -2.*e))

i guess that might be because the "show" command before the loop blocks
the program.
you can omit the line with "show" or start ipython with

Hey everyone,
this is more a how-to / feature request than a question... Normally, my
workflow for embedding images in LaTeX is as follows:
1) produce ps-file
2) use pstoedit (xfig) to separate text/math (LaTeX-typesettable) from
the image
3) save as pdf_t and pdf, respectively
4) \input this in

hey thomas!
i see. perhaps xfig could then help you, it has an export to emf feature
(and can import ps files, see for example

what about convert from imagemagick? "convert test.ps test.emf" gives
some output -- if this is indeed a correct emf file i cannot tell

if your matrices a and b are rectangular (and i think the "diagonal"
makes only sense in this case), you can also say:
