Well, that was easy! So are these SAGE objects that you have to
construct? Its not clear where this code comes from. Is it a python
object, is it from maxima, gap, what?
Still, these constructs do not preserve the matrix paradigm from
MATLAB. For example, in MATLAB you can pass a matrix as an input
parameter and process all the data in the matrix. I that like a List
object in python? I thought I read somewhere in the SAGE dox that this
was possible. I don't know why I'm thinking its a scipy thing. What
do you use scipy and numpy for? BTW, does SAGE use VPython?
How about another sample:
OCTAVE INPUT FILE:
#!/usr/bin/octave -q
diary vector2.txt
%vector2.m MrG 2010.0324
%purpose: playing with the cross product
%initialize 2 vectors in R^3
a=[1 0 5]
b=[-2 1 0]
%vector cross product
c=cross(a,b)
area=norm(c)
theta1=asin(area/norm(a)/norm(b))
theta2=theta1*180/pi
%scalar dot product
d=dot(a,b)
theta3=acos(d/norm(a)/norm(b))
theta4=theta3*180/pi
%triple scalar product
e=[1 1 1]
vol=abs(dot(e,c))
%vector dilation
f=2*a
g=-3*b
OCTAVE OUTPUT FILE:
a =
1 0 5
b =
-2 1 0
c =
-5 -10 1
area = 11.225
theta1 = 1.3945
theta2 = 79.897
d = -2
theta3 = 1.7471
theta4 = 100.10
e =
1 1 1
vol = 14
f =
2 0 10
g =
6 -3 -0
