在Python中区分Hermite_e系列,设置导数并将每个导数乘以标量
要区分Hermite_e系列,可以在Python中使用hermite_e.hermeder()方法。第一个参数c是一个Hermite_e系列系数的数组。如果c是多维的,那么不同的轴对应于不同的变量,每个轴上的度由相应的索引给出。
第二个参数m是所取的导数的数量,必须是非负的。(默认值:1)第三个参数scl是一个标量,每个导数都乘以scl。最终的结果是乘以scl ** m。这用于线性变量的变换。(默认值:1)第四个参数axis是进行导数求取的轴。(默认值:0)
步骤
首先导入所需的库−
import numpy as np
from numpy.polynomial import hermite_e 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Hermite_e级数,请在Python中使用hermite_e.hermeder()方法
print("\nResult...\n",H.hermeder(c, 2, scl = -1))
示例
import numpy as np
from numpy.polynomial import hermite_e 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_e series, use the hermite_e.hermeder() method in Python
print("\nResult...\n",H.hermeder(c, 2, scl = -1))
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...
[ 6. 24.]
