区分Hermite_e级数并在Python中将每个导数乘以标量
要区分Hermite_e级数,请在Python中使用hermite_e.hermeder()方法。第一个参数c是Hermite_e级数系数的数组。如果c是多维的,则不同的轴对应不同的变量,每个轴上的度由相应的索引给出。
第二个参数m是进行的导数数量,必须是非负的(默认为1)。第三个参数scl是一个标量。每个导数都乘以scl。最终结果是乘以scl的m次幂。这适用于线性变量的变化(默认为1)。第四个参数axis是进行导数的轴。
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)
为了区分 Hermite_e series,请使用 Python 中的 hermite_e.hermeder() 方法。
print("\nResult...\n",H.hermeder(c, 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, 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...
[ -2. -6. -12.]
