In linear algebra, a Hilbert matrix, introduced by Hilbert (1894), is a square matrix with entries being the unit fractions $${\displaystyle H_{ij}={\frac {1}{i+j-1}}.}$$For example, this is the 5 × 5 Hilbert matrix: See more Hilbert (1894) introduced the Hilbert matrix to study the following question in approximation theory: "Assume that I = [a, b], is a real interval. Is it then possible to find a non-zero polynomial P with integer coefficients, such … See more • Hilbert, David (1894), "Ein Beitrag zur Theorie des Legendre'schen Polynoms", Acta Mathematica, 18: 155–159, doi:10.1007/BF02418278, ISSN 0001-5962, JFM See more The Hilbert matrix is symmetric and positive definite.

According to this paper, the answer is yes. I'm not familiar with the theorem of Nehari mentioned there; if you assume that, though, you can check that the value of g ( n) does produce the Hilbert matrix as indicated and has L ∞ norm π. (Here g ^ is the Fourier transform of g ). (The paper refers to the infinite-dimensional Hilbert matrix ...
