Apologies. Hopefully this makes more sense. I need to find a vector that cannot be formed from a linear combination of the rows in S1. It also can't be formed by a linear combination of rows in S2 or a linear combination of rows in S3. So I am trying to find a vector b such that there...

I am looking to find a vector which does not lie in various subspaces. For example, if I have: S1 = [1,0,0; 0,1,0] (x-y plane) S2 = [1,0,0; 0,0,1] (x-z plane) S3 = [0,1,0; 0,0,1] (y-z plane) I want to find a vector which was not within any of these subspaces - in this specific example...
