To multiply the Hermite series by x, where x is the independent variable, use the polynomial.hermite.hermmulx() method in Python Numpy. The method returns an array representing the result of the multiplication. The parameter, c is a 1-D array of Hermite series coefficients ordered from low to high.

Steps

At first, import the required library −

import numpy as np
from numpy.polynomial import hermite as H

Create an array −

c = np.array([1, 2, 3])

Display the array −

print("Our Array...",c)

Check the Dimensions −

print("Dimensions of our Array...",c.ndim)

Get the Datatype −

print("Datatype of our Array object...",c.dtype)

Get the Shape −

print("Shape of our Array object...",c.shape)

To multiply the Hermite series by x, where x is the independent variable, use the polynomial.hermite.hermmulx() method −

print("Result....",H.hermmulx(c))

Example

import numpy as np
from numpy.polynomial import hermite as H

# Create an array
c = np.array([1, 2, 3])

# Display the array
print("Our Array...",c)

# Check the Dimensions
print("Dimensions of our Array...",c.ndim)

# Get the Datatype
print("Datatype of our Array object...",c.dtype)

# Get the Shape
print("Shape of our Array object...",c.shape)

# To multiply the Hermite series by x, where x is the independent variable, use the polynomial.hermite.hermmulx() method in Python Numpy
print("Result....",H.hermmulx(c))

Output

Our Array...
[1 2 3]

Dimensions of our Array...
1

Datatype of our Array object...
int64

Shape of our Array object...
(3,)

Result....
[2. 6.5 1. 1.5]
