Homework Help: Vandermonde matrix

    1. The problem statement, all variables and given/known data
    From wikipedia Vandermonde matrix is a matrix for all the indices i and j Vij=ai^(j-1).

    In Matlab the function A = vander(v) returns the Vandermonde matrix whose columns are
    powers of the vector v, that is, A(i,j) = v(i)^(n-j), where n =length(v).

    2. Relevant equations


    A(i,j) = v(i)^(n-j)

    3. The attempt at a solution

    V(i,j)=a(i)^(j-1) is correct.

    Why? Is the second one wrong?
