在 Python 中向另一个 Hermite_e 级数中添加一个 Hermite_e 级数


若要向另一个 Hermite_e 级数中添加一个 Hermite_e 级数,请在 Python Numpy 中使用 polynomial.hermite.heremadd() 方法。该方法返回一个数组,表示其总和的 Hermite_e 级数。返回两个 Hermite_e 级数 c1 + c2 的总和。参数是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 + 2*P_1 + 3*P_2。参数 c1 和 c2 是从低到高排序的 Hermite_e 级数系数的一维数组。

步骤

首先,导入所需的库 -

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

创建 Hermite_e 级数系数的一维数组 -

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)

检查两个数组的维数 -

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)

若要向另一个 Hermite_e 级数中添加一个 Hermite_e 级数,请在 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))
