Owning Class: matrix

Requires: MathScript RT Module

Syntax

c = invhilbertmx(n)

Legacy Name: invhilb

Description

Computes the inverse of a Hilbert matrix whose (i, j)-th element is equal to 1/(i+j-1), where i is the row index number and j is the column index number. The Hilbert matrix is a famous example of a poorly-conditioned matrix.

Examples
