2011-06-28 19:45:38 +0200 asked a question sage vs. maxima for symbolic computation

Is there something that sage can do and maxima can´t? in other words, what are the advantages of using sage over maxima for symbolic manipulation? I´ve been using maxima for a while and I know it has some shortcomings, I´m impressed with sage and I know it uses maxima for symbolic manipulation but I would like to know if there is something to gain in moving completely to sage.

Hello, I´m trying to construct a histogram using octave within sage, but I don´t know how to use sage functions with data that comes from octave, here´s what I´m doing:

a = octave.normrnd(50,3,100,1) #this generates a column vector with normal random data
b = octave.hist(a) #this generates a histogram from the previous data

bar_chart(b)  # this is where I get the following error:

NotImplementedError: Unable to parse output

Is this something that has not been implemented as the message suggests or am I doing something wrong?

2011-06-20 21:39:57 +0200 marked best answer Sage Virtual Machine sudo password?

The new VirtualBox machine that I built (sage-4.7 and newer, .ova extension) uses sage as password for both the root and the sage user account.

The sage user is indeed not in the sudoers file, I'll add that in some future release. So you need to su first, or press Alt-F1 to get to a different tty and login as root.

excellent, worked like a charm! except that the command sudo aptitude is not valid for Fedora, but I researched a bit on the internet and used yum install.

"sage is not in the sudoers file, this incident will be reported"

nope, I already tried all 3 of them with no luck, if I enter "sage" I get the following message:
