WebA matrix A = (a(i, k)) is said to be a P-matrix if (1) A is positive (that is, all a(i, k) are positive) and (2) all minor determinants of second order a(i, k) a(i, k + 1) a(i + I, k) a(i + 1, … The Hilbert matrix is symmetric and positive definite. The Hilbert matrix is also totally positive (meaning that the determinant of every submatrix is positive). The Hilbert matrix is an example of a Hankel matrix. It is also a specific example of a Cauchy matrix. The determinant can be expressed in closed form, … See more 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, 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 Hilbert (1894) introduced the Hilbert matrix to study the following question in approximation theory: "Assume that I = [a, b], is a real interval. … See more The method of moments applied to polynomial distributions results in a Hankel matrix, which in the special case of approximating a … See more pistons greatest player against jordan
