1. ## How to find a matrix who kernel is spanned by two vectors?

Can somebody help me solve the following problem?
Find a matrix whose kernel is spanned by the two vectors x= (x1, x2, x3) and y=(y1,y2,y3).
What would be the procedure if xi and yi were some integers?
You may replace xi and yi by some integers if you think that will more easier to explain.

Thank you very much

2. $A=[\vec{x}\ \ \vec{y}]^T, find\ ker(A)\ or\ A=\vec{x}\times \vec{y}$
