在Python中對具有多維繫數的Hermite級數沿特定軸進行微分
要對Hermite級數進行微分,請在Python中使用hermite.hermder()方法。第一個引數c是Hermite級數係數的陣列。如果c是多維的,則不同的軸對應於不同的變數,每個軸的次數由相應的索引給出。
第二個引數m是導數的次數,必須是非負數。(預設值:1)。第三個引數scl是一個標量。每次微分都乘以scl。最終結果是乘以scl**m。這用於變數的線性變化。(預設值:1)。第四個引數axis是進行微分的軸。(預設值:0)。
步驟
首先,匯入所需的庫:
import numpy as np from numpy.polynomial import hermite as H
建立一個多維繫數陣列:
c = np.arange(4).reshape(2,2)
顯示陣列:
print("Our Array...\n",c)檢查維度:
print("\nDimensions of our Array...\n",c.ndim)獲取資料型別:
print("\nDatatype of our Array object...\n",c.dtype)獲取形狀:
print("\nShape of our Array object...\n",c.shape)要對Hermite級數進行微分,請在Python中使用hermite.hermder()方法:
print("\nResult...\n",H.hermder(c, axis = 1))示例
import numpy as np
from numpy.polynomial import hermite 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 series, use the hermite.hermder() method in Python
print("\nResult...\n",H.hermder(c, axis = 1))輸出
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... [[2.] [6.]]
