With the help of np.hermevander() method, we can get the pseudo vandermonde matrix at a given degree by using np.hermevander() method.
Syntax :
np.hermevander(x, deg)
Return : Return the pseudo vandermonde matrix.
Example #1 :
In this example we can see that by using np.hermevander() method, we are able to get the pseudo vandermonde matrix at a given degree by using this method.
# import numpy and hermevander import numpy as np from numpy.polynomial.hermite_e import hermevander x = np.array([0.1, 0.2, 0.3, 0.4, 0.5]) deg = 3# using np.hermevander() method gfg = hermevander(x, deg) print(gfg) |
Output :
[[ 1. 0.1 -0.99 -0.299]
[ 1. 0.2 -0.96 -0.592]
[ 1. 0.3 -0.91 -0.873]
[ 1. 0.4 -0.84 -1.136]
[ 1. 0.5 -0.75 -1.375]]
Example #2 :
# import numpy and hermevander import numpy as np from numpy.polynomial.hermite_e import hermevander x = np.array([1.1, 2.2, 3.3, 4.4, 5.5]) deg = 3# using np.hermevander() method gfg = hermevander(x, deg) print(gfg) |
Output :
[[ 1. 1.1 0.21 -1.969]
[ 1. 2.2 3.84 4.048]
[ 1. 3.3 9.89 26.037]
[ 1. 4.4 18.36 71.984]
[ 1. 5.5 29.25 149.875]]
