区分Hermite系列,并在Python中设置导数
要区分Hermite系列,请在Python中使用hermite.hermder()方法。第一个参数c是Hermite系列系数的数组。如果c是多维的,则每个轴对应不同的变量,每个轴上的次数由相应的索引给出。第二个参数m表示要求取的导数的数量,必须为非负数。 (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scl的m次幂乘积。这用于线性变量的变换。(默认值:1)。第四个参数axis是应用导数的轴。(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)
要区分一个Hermite级数,可以在Python中使用hermite.hermder()方法-
print("\nResult...\n",H.hermder(c, 3))
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, 3))
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...
[192.]
