Null space from rref
WebSyntax R = rref (A) R = rref (A,tol) [R,p] = rref (A) Description example R = rref (A) returns the reduced row echelon form of A using Gauss-Jordan elimination with partial pivoting. … Web27 dec. 2024 · The left nullspace means you have some combinations of rows of A, which the outcome is zero. Given your matrix, it is very easy to see that ( − 2, 1) works. The -2*first row + the second row = 0. I'm not writing funny things here, though I admit "observation" …
