[Tutor] Linear Algebra weirdness

[Mr Gerard Kelly]

I am getting some very strange behaviour from the Linear Algebra module.

Look at this code:

from LinearAlgebra import *

a=5
print a

And look at the output that I get when I run it:

50.0
0.0
0.25
0.0
0.5
0.0
0.75
0.0
1.0
[[  2.50000000e-01  -2.50000000e-01  -4.99993750e-01 ...,
    3.73459082e+01   3.75116710e+01   3.76764961e+01]
 [  5.00000000e-01  -5.00000000e-01  -6.25000000e-06 ...,

 [  1.00000000e+00  -1.00000000e+00   0.00000000e+00 ...,

Apparently Linear Algebra is giving me the output of another program along with the output for this one. Of course I don't need Linear Algebra to print the number 5, but I've been trying to make a program that uses Linear Algebra, and I'm always having the output come out twice each time I run it. When I edit the program, it always gives me the old output before the new output, even if I edit it right down to something as simple as "a=5, print a".

Is anybody familiar with this module and why it is doing this? I've used it before and never had this issue.
