The inverse of the Hilbert matrix can be expressed in closed form using binomial coefficients; its entries are where n is the order of the matrix. [1] It follows that the entries of the inverse matrix are all integers, and that the signs form a checkerboard pattern, being positive on the principal diagonal. For example, 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 The Hilbert matrix is symmetric and positive definite.

WebJan 22, 2024 · To abbreviate my post here, a determinant-free proof that the inverse of the Hilbert matrix has integer entries. Consider the inner product f, g = ∫ 0 1 f g on nice enough functions. The n × n Hilbert matrix H has i j entry (running the labels from zero to n − 1) x i, x j . This makes it a Gramian matrix. WebDescription. H = invhilb (n) generates the exact inverse of the exact Hilbert matrix for n less than about 15. For larger n, the invhilb function generates an approximation to the inverse Hilbert matrix. H = invhilb (n,classname) returns a matrix of class classname, which can be either 'single' or 'double'.
