Vandermonde matrix
v = vander(x) v = vander(x, n)
real or complex vector
integer value, the number of columns of y.
By default, n is equal to size(x, "*")
number of rows of x xn matrix
v = vander(x [,n]) returns the Vandermonde matrix. The columns of y
are powers of the x vector.
The Vandermonde matrix is a matrix defined by 
, i.e
.
If n is specified, the Vandermonde matrix will have n columns. By default, the
Vandermonde matrix is a square matrix.
Vandermonde matrix with vector
x = 1:5 v = vander(x) |  |  |
Vandermonde matrix with n columns
x = 2:2:10 n = 3; v = vander(x, n) | | |
