Oop got it working. Thanks for the references. Haven't tried notebook
yet save to create an admin password. I never liked zork (adventure)
this is like that but I managed this time. Now I just have to discover
how to control the argument types, Tableau matrix in QQ, pr and pc
integers. Thanks.

Have you tried using the Sage notebook?

I'm coming from writing Visual Basic code and am clueless about
python. I typed this into KWrite and saved it with .sage extension. I
used tab to indent and I am used to closing if then with an endif
statement, likewise I'm used to ending an for next statement with next
i etc.
def nx(Tableau,int
Problem solved. It turns out there is a stand-alone version of Jmol
for Linux.
Best.

Hi Mladen!
It is not a bug. Since "range" returns Python integers (type "int")
and since 1/2 is zero for Python integers, that behaviour is expected:
sage: [type(x) for x in range(3)]
[, , ]
sage: int(1)/int(2)
0
If you want a range of Sage integers (type "Integer"), use srange:
sage: [type(x)
Hi,
I think the following is a bug. Most of the time 1/2 is not declared
to be 0, but it is in the following code:
In [1]: L=[]
In [2]: for a in range
(1,2):
: for b in range
(2,3):
: L.append
([a,b])
:
In [3]:
L
Out[3]: [[1, 2]]
In [4]: for item in
L:
: print ite

perhaps print "\\frac{",a,"-(",b,")}{",c,"-",d,"}=",(a-b)/(c-d) if
b<0

That's a useful idea. Despite having implemented that feature, I

Note that your answer and my answer both suffer from not getting the
matrix into "true"
sage: R. = PolynomialRing(QQ,"a")
sage: A=matrix([[0,1,1],[2,2,-2],[-1,a,3]])
sage: A.echelon_form()
[ 2 2 -2]
[ 0 -1 -1]
[ 0 0 -a + 1]

You can also use sufficiently random and long names in temp directory
and in cron daemon clean this director
I think that you can use custom css file in your .sage directory.
I do not remember he name of this file, try to seach this group, it
has been dicussed - here or in sage-devel
