Web1 de jul. de 2014 · The inversion of the Vandermonde matrix has received much attention for its role in the solution of some problems of numerical analysis and control theory. 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. . Furthermore, …
Web13 de abr. de 2024 · Therefore, the analytic form avoids the numerical matrix inversion and can significantly reduce absolute errors compared with the Matlab functions inv and mldivide. The syntax is the same as the Matlab built-in function vander. The input is a vector v: B = invvander (v) returns the inversed Vandermonde Matrix.
