WebSep 14, 2024 · In fact, the two solutions represent the same vector space. Converting both to orthogonal projections we see that they are the same so they project onto the same space hence m1 and m2 span the same space. Web(b) A and AT have the same left nullspace. FALSE. Counterexample: Take any a 1x2 matrix, such as A = 1 1. The left nullspace of A contains vectors in R while the left nullspace of AT, which is the right nullspace of A, contains vectors in R2, so they cannot be the same. (c)If the row space equals the column space then AT = A. FALSE. ohair wards funeral https://rocketecom.net

WebApr 14, 2012 · Answers and Replies. The rref of A is of the form GA for some invertible matrix G, so the solution sets to Ax=b and rref (A)x=b will generally be different. The precise fact to note is: if Ax=b then rref (A)x= (GA)x=G (Ax)=Gb. Note that if b=0 then the previous computation yields rref (A)x=0; and conversely, if rref (A)x=0 then Ax=0.
