使用 Python 将多项式转换为埃尔米特级数
若要将多项式转换为埃尔米特级数,请在 Python Numpy 中使用 hermite.poly2herm() 方法。将表示从低到高阶排序的多项式系数的数组转换为从低到高阶排序的等效埃尔米特级数系数的数组。该方法返回一个包含等效埃尔米特级数系数的一维数组。pol 参数是一个包含多项式系数的一维数组
步骤
首先,导入所需的库 −
import numpy as np from numpy.polynomial import hermite as H
使用 numpy.array() 方法创建数组 −
c = np.array([1, 2, 3, 4, 5])
显示数组 −
print("Our Array...\n",c)检查维度 −
print("\nDimensions of our Array...\n",c.ndim)
获取数据类型 −
print("\nDatatype of our Array object...\n",c.dtype)获取形状 −
print("\nShape of our Array object...\n",c.shape)
若要将多项式转换为埃尔米特级数,请在 Python Numpy 中使用 hermite.poly2herm() 方法 −
print("\nResult (polynomial to hermite)...\n",H.poly2herm(c))示例
import numpy as np
from numpy.polynomial import hermite as H
# Create an array using the numpy.array() method
c = np.array([1, 2, 3, 4, 5])
# Display the array
print("Our Array...\n",c)
# Check the Dimensions
print("\nDimensions of our Array...\n",c.ndim)
# Get the Datatype
print("\nDatatype of our Array object...\n",c.dtype)
# Get the Shape
print("\nShape of our Array object...\n",c.shape)
# To convert a polynomial to a Hermite series, use the hermite.poly2herm() method in Python Numpy
print("\nResult (polynomial to hermite)...\n",H.poly2herm(c))输出
Our Array... [1 2 3 4 5] Dimensions of our Array... 1 Datatype of our Array object... int64 Shape of our Array object... (5,) Result (polynomial to hermite)... [6.25 4. 4.5 0.5 0.3125]
