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. The Hilbert matrix is also totally positive (meaning that the determinant of every submatrix is positive).

Compute the inverse of the Hilbert matrix of order n. The entries in the inverse of a Hilbert matrix are integers. When n is greater than 14, some entries in the inverse exceed the upper limit of 64 bit integers. The exact argument provides two options for dealing with these large integers.

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'.
