在Python中将一个拉盖尔级数加到另一个上

要将一个拉盖尔级数加到另一个上，可以使用Python Numpy库中的polynomial.laguerre.lagadd()方法。该方法返回一个表示它们和的拉盖尔级数的数组。

返回两个拉盖尔级数c1 + c2的和。参数为按照从最低阶项到最高阶项排序的系数序列，例如[1,2,3]表示级数P_0 + 2P_1 + 3P_2。参数c1和c2是按照低到高排序的1-D数组，表示拉盖尔级数的系数。

步骤

首先，导入所需的库-

import numpy as np
from numpy.polynomial import laguerre as L

创建拉盖尔级数系数的1-D数组−

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

展示系数数组 −

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)

检查两个数组的尺寸 –

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)

要将一个拉盖尔级数添加到另一个级数中，请使用polynomial.laguerre.lagadd()方法。

print("\nResult (sum)....\n",L.lagadd(c1, c2))

示例

import numpy as np
from numpy.polynomial import laguerre as L

# Create 1-D arrays of Laguerre 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 Laguerre series to another, use the polynomial.laguerre.lagadd() method in Python Numpy
# The method returns an array representing the Laguerre series of their sum.
print("\nResult (sum)....\n",L.lagadd(c1, c2))
