Python 对具有多维系数的Hermite_e序列进行特定轴的求导
要对Hermite_e序列进行求导,可以使用Python中的hermite_e.hermeder()方法。第一个参数c是Hermite_e系列系数的数组。如果c是多维的,则不同的轴对应不同的变量,每个轴的阶数由相应的索引给出。
第二个参数m是需要求导的次数,必须为非负数(默认值为1)。第三个参数scl是一个标量。每次求导都会乘以scl。最终结果是乘以scl的m次方。这用于线性变量变换(默认值为1)。第四个参数axis是要对其进行导数的轴(默认值为0)。
步骤
首先,导入所需的库−
import numpy as np
from numpy.polynomial import hermite_e as H
创建一个多维系数数组 –
c = np.arange(4).reshape(2,2)
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)
要区分Hermite_e系列,可以在Python中使用hermite_e.hermeder()方法
print("\nResult...\n",H.hermeder(c, axis = 1))
示例
import numpy as np
from numpy.polynomial import hermite_e as H
# Create a multidimensional array of coefficients
c = np.arange(4).reshape(2,2)
# 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 differentiate a Hermite_e series, use the hermite_e.hermeder() method in Python
print("\nResult...\n",H.hermeder(c, axis = 1))
输出
Our Array...
[[0 1]
[2 3]]
Dimensions of our Array...
2
Datatype of our Array object...
int64
Shape of our Array object...
(2, 2)
Result...
[[1.]
[3.]]
