Hi:
I see an principle about rank one matrice in the book, and it says
if u=(1,2,3), [itex]\nu[/itex]t=[1 3 10], with Ax=0,
the equation [itex]\nu[/itex]tx=0;
The problem is I see an example like following:
s1=[-3
1
0]
s2=[-10
0
1]
The nullspace contains all combination of s1 and s2. and produces the plane
x+3y+10z=0, perpendicular to row(1,3,10). And it lead to the result
Nullspace perpendicular to row space. I didn't know what the result means and
how its imply, could anyone give me any instruct about that, thanks.
