**The inverse matrix of Vandermonde matrix**

being a lower triangular matrix. L. Richard [10] wrote the inverse of the Vandermonde matrix as a product of two triangular matrices. F. Soto and H. Moya [13] showed that V 1 = DWL, where D is a diagonal matrix, W is an upper triangular matrix and L is a lower triangular matrix. However, in all of these techniques V 1 is not determined ...
