Cauchy matrix

In mathematics, a Cauchy matrix, named after Augustin Louis Cauchy, is an m×n matrix with elements a_ij in the form

where $x_i$ and $y_j$ are elements of a field $\mathcal{F}$ , and $(x_i)$ and $(y_j)$ are injective sequences (they contain distinct elements).

The Hilbert matrix is a special case of the Cauchy matrix, where
