As for the QR, you can indeed choose to use it to find a basis for null space for the transpose of Q with columns corresponding to zeros in R. $\endgroup$ – Jimmy Xiao May 4, 2016 at 11:23 What is an eigenspace of an eigen value of a matrix? (Definition) For a matrix M M having for eigenvalues λi λ i, an eigenspace E E associated with an eigenvalue λi λ i is the set (the basis) of eigenvectors →vi v i → which have the same eigenvalue and the zero vector. That is to say the kernel (or nullspace) of M −Iλi M − I λ i.The point of saying that N (A) = N (rref (A)) is to highlight that these two different matrices in fact have the same null space. This means that instead of going through the process of creating the augmented matrix and carrying around all those zeros, you can find rref (A) first and then find the null space of that. In this video, I define the left null space of a matrix. I then work through several examples in which I find the left null space of a matrix and a basis fo...

We should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0. Null Space of Matrix.
