法律研究在Python中將一個埃爾米特級數乘以另一個埃爾米特級數
要將一個埃爾米特級數乘以另一個，請在Python Numpy中使用polynomial.hermite.hermmul()方法。此方法返回一個數組，表示其乘積的埃爾米特級數。返回兩個埃爾米特級數c1 * c2的乘積。引數是從最低項到最高項的係數序列，例如[1,2,3]表示級數P_0 + 2*P_1 + 3*P_2。引數是從低到高排序的埃爾米特級數係數的1-D陣列。
步驟
首先，匯入所需的庫−
import numpy as np from numpy.polynomial import hermite as H
建立埃爾米特級數係數的1-D陣列−
c1 = np.array([1,2,3]) c2 = np.array([3,2,1])
顯示係數陣列−
print("Array1...\n",c1)
print("\nArray2...\n",c2)顯示資料型別−
print("\nArray1 datatype...\n",c1.dtype)
print("\nArray2 datatype...\n",c2.dtype)檢查兩個陣列的維度−
print("\nDimensions of Array1...\n",c1.ndim)
print("\nDimensions of Array2...\n",c2.ndim)檢查兩個陣列的形狀−
print("\nShape of Array1...\n",c1.shape)
print("\nShape of Array2...\n",c2.shape)要將一個埃爾米特級數乘以另一個，請在Python Numpy中使用polynomial.hermite.hermmul()方法−
print("\nResult (multiply)....\n",H.hermmul(c1, c2))示例
import numpy as np
from numpy.polynomial import hermite as H
# Create 1-D arrays of Hermite series coefficients
c1 = np.array([1,2,3])
c2 = np.array([3,2,1])
# Display the arrays of coefficients
print("Array1...\n",c1)
print("\nArray2...\n",c2)
# Display the datatype
print("\nArray1 datatype...\n",c1.dtype)
print("\nArray2 datatype...\n",c2.dtype)
# Check the Dimensions of both the arrays
print("\nDimensions of Array1...\n",c1.ndim)
print("\nDimensions of Array2...\n",c2.ndim)
# Check the Shape of both the arrays
print("\nShape of Array1...\n",c1.shape)
print("\nShape of Array2...\n",c2.shape)
# To multiply one Hermite series to another, use the polynomial.hermite.hermmul() method in Python Numpy
# The method returns an array representing the Hermite series of their product.
print("\nResult (multiply)....\n",H.hermmul(c1, c2))輸出
Array1... [1 2 3] Array2... [3 2 1] Array1 datatype... int64 Array2 datatype... int64 Dimensions of Array1... 1 Dimensions of Array2... 1 Shape of Array1... (3,) Shape of Array2... (3,) Result (multiply).... [35. 40. 38. 8. 3.]
