移除Python中Hermite_e多項式的尾部小系數
要移除Hermite_e多項式的尾部小系數,請在Python NumPy中使用hermite_e.hermetrim()方法。該方法返回一個已去除尾部零的1維陣列。如果生成的序列為空,則返回包含單個零的序列。
“小”表示“絕對值小”,由引數tol控制;“尾部”表示最高階係數,例如,在[0, 1, 1, 0, 0](表示0 + x + x**2 + 0*x**3 + 0*x**4)中,第3階和第4階係數都將被“修剪”。引數c是一個從低階到高階排序的1維繫數陣列。引數tol是:絕對值小於或等於tol的尾部元素將被移除。
步驟
首先,匯入所需的庫:
import numpy as np from numpy.polynomial import hermite_e as H
使用numpy.array()方法建立一個數組。這是一個1維繫數陣列:
c = np.array([0,5,0, 0,9,0])
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)要移除Hermite_e多項式的尾部小系數,請在Python中使用hermite_e.hermetrim()方法:
print("\nResult...\n",H.hermetrim((c)))示例
import numpy as np
from numpy.polynomial import hermite_e as H
# Create an array using the numpy.array() method
# This is the 1-d array of coefficients
c = np.array([0,5,0, 0,9,0])
# 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 remove small trailing coefficients from Hermite_e polynomial, use the hermite_e.hermetrim() method in Python Numpy.
print("\nResult...\n",H.hermetrim((c)))輸出
Our Array... [0 5 0 0 9 0] Dimensions of our Array... 1 Datatype of our Array object... int64 Shape of our Array object... (6,) Result... [0. 5. 0. 0. 9.]
