Actually:

octave:2> x = 1
x =  1
octave:3> u = 3
u =  3
octave:4> p = 4
p =  4
octave:5> y = [x u p
> p x u
> u u p]
y =

   1   3   4
   4   1   3
   3   3   4

So that's probably not the problem.  I don't know enough about load
flow to help more with that, but I think you are going about the
task wrong -- you write a big block of code and then wonder why it
doesn't work, when you should be starting with a very simple
problem and then add to it until it does what you want.  If you
have to, type each line into the interpreter and see if what comes
out is what you expected.  If you don't know what to expect, then
you don't know enough about the problem to even start coding.
