在Python中对多维系数的Hermite级数进行轴1的求导
要对Hermite级数进行求导,可以使用Python中的hermite.hermder()方法。第一个参数c是一个Hermite级数系数的数组。如果c是多维的,不同的轴对应于不同的变量,每个轴上的次数由对应的索引给出。第二个参数m是要求取的导数的数量,必须是非负的。(默认值: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:1)。第四个参数axis是要对其进行导数的轴。(默认值:0)。
步骤
首先,导入所需的库−
import numpy as np
from numpy.polynomial import hermite 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)
使用Python中的hermite.hermder()方法区分Hermite级数-
print("\nResult...\n",H.hermder(c, axis = 1))
示例
import numpy as np
from numpy.polynomial import hermite 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 series, use the hermite.hermder() method in Python
print("\nResult...\n",H.hermder(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...
[[2.]
[6.]]
