Python | Numpy np.hermvander() method

With the help of np.hermvander() method, we can get the pseudo vandermonde matrix from hermite series of given degree by using np.hermvander() method.

Syntax : np.hermvander(x, deg)
Return : Return the pseudo vandermonde matrix of given degree.

Example #1 :
In this example we can see that by using np.hermvander() method, we are able to get the pseudo vandermonde matrix of hermite series by using this method.

x = np.array([1, 2, 3, 5, 7, 11])
deg = 2
  
# using np.hermvander() method
gfg = hermvander(x, deg)
  
print(gfg)
