Homework Statement
Supposedly the process to solve Ax=0 is to solve Transpose(R).Ry=z (where z is a random vector) and then x=y/(norm-2 of y).
Homework Equations
The Attempt at a Solution
Ay=b for some random vector b
Transpose(A).Ay= Transpose(A).b
Transpose(QR).QRy=Transpose(A).b
Transpose(R).Transpose(Q).QRy = z where z is Transpose(A).b
Transpose(R).Ry=z since Q is orthogonal
Then x (the solution to the homogeneous system) is y/(norm-2 y)? But why?
