Suppose A is an m n matrix of rank r < n. Prove that there exist
Question:
Suppose A is an m × n matrix of rank r < n. Prove that there exist arbitrarily close matrices of maximal rank, that is, for every ε > 0 there exists an m × n matrix B with rank B = n such that the Euclidean matrix norm ΙΙ A − B ΙΙ < ε.
