在Python中将一个Hermite级数添加到另一个中

要将一个Hermite级数添加到另一个级数中，可以使用Python Numpy中的polynomial.hermite.hermadd()方法。该方法返回表示它们和的Hermite级数的数组。返回两个Hermite级数c1 + c2的和。参数是按照从最低阶项到最高阶项排序的系数序列，即[1,2,3]表示级数P_0 + 2P_1 + 3P_2。参数c1和c2是按照从低到高排序的Hermite级数系数的1-D数组。

步骤

首先，导入所需的库 −

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

创建一维的Hermite级数系数数组 –

c1 = np.array([1,2,3])
c2 = np.array([3,2,1])

显示系数数组 –

print("Array1...\n",c1)
print("\nArray2...\n",c2)

显示数据类型 –

print("\nArray1 datatype...\n",c1.dtype)
print("\nArray2 datatype...\n",c2.dtype)

检查两个数组的维度 –

print("\nDimensions of Array1...\n",c1.ndim)
print("\nDimensions of Array2...\n",c2.ndim)

检查两个数组的形状 –

print("\nShape of Array1...\n",c1.shape)
print("\nShape of Array2...\n",c2.shape)

将一个Hermite级数添加到另一个Hermite级数中，请使用Python的polynomial.hermite.hermadd()方法 Numpy库 −

print("\nResult (sum)....\n",H.hermadd(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 add one Hermite series to another, use the polynomial.hermite.hermadd() method in Python Numpy
# The method returns an array representing the Hermite series of their sum.
# Returns the sum of two Hermite series c1 + c2. The arguments are
print("\nResult (sum)....\n",H.hermadd(c1, c2))
