Hi:(adsbygoogle = window.adsbygoogle || []).push({});

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]^{t}x=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 any one give me any instruct about that, thanks.
