“…Since Q f is a symmetric positive semidefinite M matrix, G is a positive definite M matrix and G s = √ G is also a positive definite M matrix [25], and all of its entries are non-zero [23]. Using Lemma 5.5 of [23], G + G + 4 α √ G is an M matrix with negative off-diagonal entries.…”

“…We wish to show that lim k−→∞ T k θ exists, i.e., it is convergent 1 . This limit if it exists is a projection onto the null space of the singular matrix A.…”
