Chapter 3 Quadratic Programming
3.3.3 Null-space approach The null-space approach does not require regularity of B and thus has a wider range of applicability than the range-space approach. We assume that A 2 lRm£n has full row rank m and that ZTBZ is positive deflnite, where Z 2 lRn£(n¡m) is the matrix whose columns span Ker A which can be computed by QR factorization ...

Methods for Finding Bases - Texas A&M University
www.math.tamu.edu1 Bases for the subspaces of a matrix Row-reduction methods can be used to find bases. Let us now look at an example illustrating how to obtain bases for the row space, null space, and column space of a matrix A. To begin, we look at an example, the matrix A on the left below. If we row reduce A, the result is U on the right. A = 1 1 2 0
