Positive Semidefinite Matrix: An n× n matrix A is positive semidefinite if (i) A = A′, (ii) Y′AY≥ 0 for all n× 1 real vectors Y, and (iii) Y′AY = 0 for at least one n× 1 nonzero real vector Y. Example 1.1.9 The matrix Jn is positive semidefinite because Jn = J...
S equals A⊤A for a matrix A with independent columns. Positive Semidefinite Matrices Positive semidefinite matrices have all λ≥0 and all x⊤Sx≥0. Those weak inequalities ( ≥ instead of > ) include positive definte S and the singular matrices at the edge. ...
