在Python中对具有多维系数的Hermite_e级数沿轴1求导
在Python中,使用`hermite_e.hermeder()`方法可以对Hermite_e级数求导。第一个参数`c`是Hermite_e级数系数的数组。如果`c`是多维的,不同的轴对应于不同的变量,每个轴的阶数由相应的索引给出。
第二个参数`m`是被求导的次数,必须是非负数。(默认值:1)。第三个参数`scl`是一个标量。每次求导都乘以`scl`。最终结果是乘以`scl**m`。这是用于线性变量变化的。(默认值:1)。第四个参数`axis`是求导所沿的轴。(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
创建一个多维系数数组:
c = np.arange(4).reshape(2,2)
显示数组:
print("Our Array...\n",c)
检查维度:
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)
在Python中,使用`hermite_e.hermeder()`方法对Hermite_e级数求导:
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.]]
