matrix - People(dot)tuke(dot)sk
... Two matrices are identical if they are of the same type and if they have the same entries at corresponding position. Suppose that A = aij is an m n matrix. The entries a11, a22, a33, …, akk (where k = minm, n) form a so called main diagonal in matrix A. Štefan BEREŽNÝ ...

Numerical methods for Vandermonde systems with particular points
... This also means that the sequential implementation of the algorithm pre sented is about k times faster than the Björck-Pereyra algorithm, for Vandermonde matrices of this type when kq . In other words, the asymptotical speed-up is k. Similar considerations may be done in the symmetric case when k= ...
