On Generalized Gaussian Quadratures for Exponentials and Their Applications [PDF]
Applied and Computational Harmonic Analysis, 2002 We introduce new families of Gaussian-type quadratures for weighted integrals of exponential functions and consider their applications to integration and interpolation of bandlimited functions.We use a generalization of a representation theorem due to ...

Padé approximation and gaussian quadrature
Bulletin of the Australian Mathematical Society, 1974For certain types of formal power series, including the series of Stieltjes, we prove that the [n, n+j], j ≥ −1, Padé approximants coincide with certain gaussian quadrature formulae and hence, convergence of these approximants follows immediately.

Quadrature approximation properties of the spiral-phase quadrature transform
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011The notion of the 1-D analytic signal is well understood and has found many applications. At the heart of the analytic signal concept is the Hilbert transform. The problem in extending the concept of analytic signal to higher dimensions is that there is no unique multidimensional definition of the Hilbert transform.

A Construction of Nonnegative Approximate Quadratures [PDF]
Mathematics of Computation, 1967 Tchakaloff's demonstration is a very beautiful one, involving the theory of convex bodies. A separating hyperplane is employed and a nonconstructive proof is obtained. The theorem is valid for weighted integrals of dimension d _ 1. Equivalent results on finite moment spaces were obtained earlier by various authors.

On realizations of an approximation random quadrature formula
USSR Computational Mathematics and Mathematical Physics, 1983The coefficients \(c=\int f(x)\Phi(x)\mu(dx)\) of the least square approximation of f according to a system \(\Phi =(\phi_ 1,...,\phi_ m)\) of \(\mu\)-orthonormalized functions \(\{\phi_ k\}^ m_ 1\) satisfy a linear system of equations. The authors propose to approximate the integrals c by the solution \(\hat c\) of an approximation of this system ...
