WebVandermonde Matrix. For input vector , the Vandermonde matrix is. The matrix is described by the formula such that its columns are powers of the vector v. An alternate form of the Vandermonde matrix flips the matrix along the vertical axis, as shown. Use fliplr (vander (v)) to return this form. 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, … dragon tooth alocasia
