... the first situation in which there exist many consistent solutions. One can think of the entire set of consistent solutions as y = yR + yN where yR is the linear combination of the rows of A consistent with AyR = x and yN = NTk where k is a (n-r)-length vector of free variables or weights on the bas ...
