*is in*

**p****M**and

**M**=span{

**v***},that means*

**w****=a**

*p**+b*

**v***, right?*

**w**then, could either a or b be zero?

regarded to this following problem:

__Is is possible that {[1 2 0]^T,[2 0 3]^T} can span the subspace U={[__

*0]^T /***r s****and***r**in***s****R**}?I thought if

**s***and the scalar for [2 0 3]^T could be zero, it might be possible?*
