Python 对具有多维系数的Hermite_e级数进行沿轴1的求导
要对Hermite_e级数进行求导,在Python中使用hermite_e.hermeder()方法。第一个参数c是一维或多维Hermite_e级数系数的数组。如果c是多维的,不同的轴对应着不同的变量,每个轴的阶数由相应的索引提供。
第二个参数m是取的导数的数量,必须为非负数(默认为1)。第三个参数scl是一个标量,每次求导结果都会乘以scl,最终结果是scl的m次方。这用于线性变量的变换(默认为1)。第四个参数axis是要对其进行求导的轴(默认为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)
为了区分Hermite_e系列,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.]]
