在Python中将一个切比雪夫级数除以另一个

要将一个切比雪夫级数除以另一个，请使用Python NumPy中的polynomial.chebyshev.chebdiv（）方法。该方法返回表示商和余项的切比雪夫级数系数数组。

返回两个切比雪夫级数c1 / c2的商和余数。参数是从最低阶“项”到最高阶的系数序列，例如，[1,2,3]表示系数为T_0 + 2*T_1 + 3*T_2的级数。参数c1和c2是按从低到高排序的切比雪夫级数系数的1-D数组。

步骤

首先，导入所需的库 –

import numpy as np
from numpy.polynomial import chebyshev as C

创建1-D数组的切比雪夫级数系数−

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)

要将一个切比雪夫级数除以另一个，请使用Python中的polynomial.chebyshev.chebdiv（）方法−

print("\nResult (division)....\n",C.chebdiv(c1,c2))

例子

import numpy as np
from numpy.polynomial import chebyshev as C

# 创建1-D数组的切比雪夫级数系数
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)

# 要将一个切比雪夫级数除以另一个，请使用Python NumPy中的polynomial.chebyshev.chebdiv（）方法
print("\nResult (division)....\n",C.chebdiv(c1,c2))
