On the inversion of the vandermonde matrix

WebFast inversion algorithms for strongly nonsingular matrices of the form \(C = \left[ {\frac{{z_i^T{y_j}}}{{{c_i} - {d_j}}}} \right]\) (generalized Cauchy matrices), where z i, y j are column vectors and c i, d j are complex numbers, are presented. The approach is based on the interpretation of equations Cξ = η as tangential interpolation problems. .
