在 Python 中将多项式转换为 Hermite_e 级数
要将多项式转换为 Hermite 级数,请在 Python Numpy 中使用 hermite_e.poly2herme() 方法。将表示从低次到高次排列的多项式的系数的数组转换为等效 Hermite 级数的系数的数组,从低次到高次排列。该方法返回一个包含等效 Hermite 级数系数的 1-D 数组。参数 pol 是一个包含多项式系数的 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
使用 numpy.array() 方法创建一个数组−
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)
要将多项式转换为 Hermite 级数,请在 Python Numpy 中使用 hermite_e.poly2herme() 方法。将表示从低次到高次排列的多项式的系数的数组转换为等效 Hermite 级数的系数的数组,从低次到高次排列 −
print("\nResult (polynomial to hermite_e)...\n",H.poly2herme(c))
示例
import numpy as np from numpy.polynomial import hermite_e 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_e.poly2herme() method in Python Numpy print("\nResult (polynomial to hermite_e)...\n",H.poly2herme(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_e)... [19. 14. 33. 4. 5.]
