在 Python 中將一個 Hermite_e 級數乘以另一個
要將一個 Hermite_e 級數乘以另一個,請在 Python Numpy 中使用 polynomial.hermite.hermemul() 方法。該方法返回一個數組,表示其乘積的 Hermite_e 級數。返回兩個 Hermite_e 級數 c1 * c2 的乘積。引數是有序的係數組合,從最低階“項”到最高階,例如 [1,2,3] 表示級數 P_0 + 2*P_1 + 3*P_2。低到高的 Hermite_e 級數係數的一維陣列。
步驟
首先,匯入所需的庫−
import numpy as np from numpy.polynomial import hermite_e as H
建立 Hermite_e 級數係數的一維陣列−
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 Hermite_e 級數乘以另一個,請在 Python Numpy 中使用 polynomial.hermite.hermemul() 方法−
print("\nResult (multiply)....\n",H.hermemul(c1, c2))示例
import numpy as np
from numpy.polynomial import hermite_e as H
# Create 1-D arrays of Hermite_e 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_e series to another, use the polynomial.hermite.hermemul() method in Python Numpy
print("\nResult (multiply)....\n",H.hermemul(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).... [13. 24. 26. 8. 3.]
