To raise a Laguerre series to a power, use the polynomial.laguerre.lagpow() method in Python Numpy. The method returns the Laguerre series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1,2,3] is the series P_0 + 2*P_1 + 3*P_2.
Returns the Laguerre series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1,2,3] is the series P_0 + 2*P_1 + 3*P_2. The parameter, c is a 1-D array of Laguerre series coefficients ordered from low to high. The parameter, pow is a Power to which the series will be raised. The parameter, maxpower is the maximum power allowed. This is mainly to limit growth of the series to unmanageable size. Default is 16
Steps
At first, import the required library −
import numpy as np from numpy.polynomial import laguerre as L
Create 1-D arrays of Laguerre series coefficients −
c = np.array([1,2,3])
Display the coefficient array −
print("Our coefficient Array...\n",c)
Check the Dimensions −
print("\nDimensions of our Array...\n",c.ndim)
Get the Datatype −
print("\nDatatype of our Array object...\n",c.dtype)
Get the Shape −
print("\nShape of our Array object...\n",c.shape)
To raise a Laguerre series to a power, use the polynomial.laguerre.lagpow() method in Python Numpy −
print("\nResult....\n",L.lagpow(c, 3))
Example
import numpy as np from numpy.polynomial import laguerre as L # Create 1-D arrays of Laguerre series coefficients c = np.array([1,2,3]) # Display the coefficient array print("Our coefficient Array...\n",c) # Check the Dimensions print("\nDimensions of our Array...\n",c.ndim) # Get the Datatype print("\nDatatype of our Array object...\n",c.dtype) # Get the Shape print("\nShape of our Array object...\n",c.shape) # To raise a Laguerre series to a power, use the polynomial.laguerre.lagpow() method in Python Numpy print("\nResult....\n",L.lagpow(c, 3))
Output
Our coefficient Array... [1 2 3] Dimensions of our Array... 1 Datatype of our Array object... int64 Shape of our Array object... (3,) Result.... [ 150. -1116. 4590. -9672. 11934. -8100. 2430.]
