将Hermite_e级数转换为Python中的多项式
要将Hermite_e级数转换为多项式,在Python Numpy中使用hermite_e.herme2poly()方法。将表示Hermite_e级数系数的数组,从最低度到最高度进行排序,转换为表示等效多项式系数的数组(相对于“标准”基础),从最低到最高度进行排序。该方法返回一个包含等效多项式系数的一维数组(相对于“标准”基础),从最低阶项到最高项进行排序。参数c是一个包含Hermite系数的一维数组,从最低阶项到最高项进行排序。
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)
检查尺寸 –
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Hermite_e系列转换为多项式,请在Python中使用hermite_e.herme2poly()方法。
print("\nResult (hermite_e to polynomial)...\n",H.herme2poly(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 Hermite_e series to a polynomial, use the hermite_e.herme2poly() method in Python Numpy
print("\nResult (hermite_e to polynomial)...\n",H.herme2poly(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 (hermite_e to polynomial)...
[ 13. -10. -27. 4. 5.]
