Python | Numpy np.hermvander2d() method Last Updated : 29 Dec, 2019 Comments Improve Suggest changes Like Article Like Report With the help of np.hermvander2d() method, we can get the 2-D pseudo vandermonde matrix from hermite series of given degree by using np.hermvander2d() method. Syntax : np.hermvander2d(x, y, deg) Return : Return the 2-D pseudo vandermonde matrix of given degree. Example #1 : In this example we can see that by using np.hermvander2d() method, we are able to get the 2-D pseudo vandermonde matrix of hermite series by using this method.
