在 Python 中向另一個 Hermite_e 級數中新增一個 Hermite_e 級數


若要向另一個 Hermite_e 級數中新增一個 Hermite_e 級數,請在 Python Numpy 中使用 polynomial.hermite.heremadd() 方法。該方法返回一個數組,表示其總和的 Hermite_e 級數。返回兩個 Hermite_e 級數 c1 + c2 的總和。引數是從最低階項到最高階項排序的係數序列,即 [1,2,3] 表示級數 P_0 + 2*P_1 + 3*P_2。引數 c1 和 c2 是從低到高排序的 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)

檢查兩個陣列的維數 -

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)

若要向另一個 Hermite_e 級數中新增一個 Hermite_e 級數,請在 Python Numpy 中使用 polynomial.hermite.heremadd() 方法 -

print("\nResult (sum)....\n",H.hermeadd(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 add one Hermite_e series to another, use the polynomial.hermite.heremadd() method in Python Numpy
print("\nResult (sum)....\n",H.hermeadd(c1, c2))
