Python 通过一个独立变量来乘以一个切比雪夫级数

要通过一个独立变量来乘以一个切比雪夫级数，在Python的Numpy中使用polynomial.chebyshev.chebmulx()方法。该方法返回一个代表乘法结果的数组。参数c1和c2是按照从低到高排序的切比雪夫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 chebyshev as C

创建一个数组 –

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

显示数组 –

print("Our Array...\n",x)

检查尺寸 –

print("\nDimensions of our Array...\n",x.ndim)

获取数据类型 –

print("\nDatatype of our Array object...\n",x.dtype)

获取形状 –

print("\nShape of our Array object...\n",x.shape)

要将Chebyshev系列与自变量相乘，请使用polynomial.chebyshev.chebmulx()方法−

print("\nResult....\n",C.chebmulx(x))

示例

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

# Create an array
x = np.array([1, 2, 3])

# Display the array
print("Our Array...\n",x)

# Check the Dimensions
print("\nDimensions of our Array...\n",x.ndim)

# Get the Datatype
print("\nDatatype of our Array object...\n",x.dtype)

# Get the Shape
print("\nShape of our Array object...\n",x.shape)

# To multiply a Chebyshev series by an independent variable, use the polynomial.chebyshev.chebmulx() method in Python Numpy

# The method returns an array representing the result of the multiplication.
print("\nResult....\n",C.chebmulx(x))

输出

Our Array...
[1 2 3]

Dimensions of our Array...
1

Datatype of our Array object...
int64

Shape of our Array object...
(3,)

Result....
[1. 2.5 1. 1.5]
