“…In section 7 we prove that BD(V ) and BD(C), and in turn the eigenvalues and the singular values of V and C, will be computed accurately. Similar accurate formulas for BD(A) may be obtained when A is a TP generalized Vandermonde [13] or a Cauchy-Vandermonde [33] matrix.…”

“…Linear system solving. The fast and accurate solution of structured linear systems is a problem that has been studied in the field of numerical linear algebra for different types of structured matrices (see, for example, [5,6,14,33]). Now we Let Ax = b be a linear system whose coefficient matrix A is a square BernsteinVandermonde matrix of order n + 1 generated by the nodes {x i } 1≤i≤n+1 , where 0 < x 1 < · · · < x n+1 < 1.…”

“…The following theorem, which is analogous to Theorem 2.1 in [11] for the case of Cauchy-Vandermonde matrices, gives us the bidiagonal factorization of the inverse of a Bernstein-Vandermonde matrix: Theorem 3.1 Let A = (a i,j ) 1≤i,j≤n+1 be a Bernstein-Vandermonde matrix whose nodes satisfy 0 < x 1 < x 2 < . .…”
