Homework Statement
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).
Homework Equations
V(i,j)=a(i)^(j-1)
A(i,j) = v(i)^(n-j)
The Attempt at a Solution
V(i,j)=a(i)^(j-1) is correct.
Why? Is the second one wrong?
