ON APPROXIMATION OF FUNCTIONS BY EXPONENTIAL SUMS 1
... The approach in this paper has grown from that in [10] where we used properties of bandlimited functions and of Hermitian Toeplitz matrices to construct solutions of (1.5). Such a construction leads to specific solutions with nodes on the unit circle and positive weights, but not necessarily with th ...

Linear Algebra In Dirac Notation
... Figure 3.1: Illustrating (a) an orthogonal (perpendicular) projection onto P; (b) a nonorthogonal projection represented by Q. already on P leaves it unchanged, corresponding to the fact that P acts as the identity operation for elements of this subspace. For this reason, P P |ωi is always the s ...
