在Python中区分Hermite级数
要区分Hermite级数,可以使用Python中的hermite.hermder()方法。第一个参数c是Hermite级数系数的数组。如果c是多维的,则不同的轴对应于不同的变量,每个轴的度由相应的索引给出。第二个参数m是取的导数次数,必须是非负数。(默认值:1)第三个参数scl是一个标量。每个导数都会乘以scl。最终结果是乘以scl的m次方。这是用于线性变量的变换。(默认值:1)第四个参数axis是取导数的轴。(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
创建一个系数的数组 −
c = np.array([1,2,3,4])
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)
要对Hermite系列进行区分,可以使用Python中的hermite.hermder()方法。
print("\nResult...\n",H.hermder(c))
示例
import numpy as np
from numpy.polynomial import hermite as H
# Create an array of coefficients
c = np.array([1,2,3,4])
# 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))
输出
Our Array...
[1 2 3 4]
Dimensions of our Array...
1
Datatype of our Array object...
int64
Shape of our Array object...
(4,)
Result...
[ 4. 12. 24.]
