Web7 jun. 2010 · The uppermost Answer is correct in that sense that usually you write u*s*vh = A and vh is returned, and this answer discusses v AND NOT vh. To make a long story short: if you have matrices u,s,v such that u*s*v = A, then the last rows of v, not the last colums of v, describe the nullspace. WebThe null space of A is the set of all vectors that are a member of -- we generally say Rn, but this is a 3 by 4 matrix, so these are all the vectors that are going to be members of R4, because I'm using this particular A, such that my matrix A times any of these vectors is …
