A different approach that might actually teach you more would be to download the current version of vmware server from here: http://www.vmware.com/download/server/ Then install a minimal version of Linux (I would suggest Ubuntu 8.04) and install the SAGE source code under it. No more need to rel

I think that as matrix(v) returns a row matrix while transpose(v) returns a column suggests that "someone" is thinking of vectors as row-matrices! Which is not surprising given the way solve(matrix,vector) works. John 2008/9/7 Jason Merrill <[EMAIL PROTECTED]>: > > On Sep 7, 6:30 am, "John Crem

As a additional information - the plot3d() method of RubiksCube uses jmol and this seems to work ok (this is sage 3.1.1) so the problem seems not to be jmol or the platform. On Sep 6, 5:20 pm, "Timothy Clemans" <[EMAIL PROTECTED]> wrote: > This is a known problem. Unfortunately there is several n

The symbolic ring is not the most obvious place to do arithmetic operations such as reducing one thing modulo another: that's a job for a polynomial ring: sage: R.=QQ[] sage: x%y x sage: y%x y sage: def proc(a,b): return a%b : sage: proc(x,y) x sage: proc(y,x) y John 2008/9/7 Rolandb <[EMA

It should be lightly easier than it is to convert a vector of length n to either an nx1 matrix or a 1xn matrix: sage: v = vector(srange(5)) sage: v (0, 1, 2, 3, 4) sage: matrix(QQ,1,5,[v]) [0 1 2 3 4] sage: matrix(QQ,5,1,list(v)) [0] [1] [2] [3] [4] I got neither of those right the first time!
