在Python中从一个Hermite_e级数中减去另一个

要从一个Hermite_e级数中减去另一个，请使用Python Numpy中的polynomial.hermite.hermesub()方法。该方法返回表示它们差异的Hermite_e级数的数组。返回两个Hermite_e级数c1-c2的差异。系数序列从低阶项到高阶项，即[1,2,3]表示系列P_0+2P_1+3P_2。参数c1和c2是按顺序排列的Hermite_e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_e as H

创建Hermite_e级数系数的1-D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)

要从一个Hermite_e级数中减去另一个，请使用Python Numpy中的polynomial.hermite.hermesub()方法−

print("\nResult (difference)....\n",H.hermesub(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 subtract one Hermite_e series to another, use the polynomial.hermite.hermesub() method in Python Numpy
print("\nResult (difference)....\n",H.hermesub(c1, c2))
