在 Python 中將一個 Hermit 級數加到另一個級數上


若要將一個 Hermit 級數加到另一個級數上,請在 Python Numpy 中使用 polynomial.hermite.hermadd() 方法。方法返回一個數組,該陣列表示其和的 Hermit 級數。返回兩個 Hermit 級數 c1 + c2 的和。引數是從最低階項到最高階項排列的係數序列,例如,[1,2,3] 表示級數 P_0 + 2*P_1 + 3*P_2。引數 c1 和 c2 是 Hermit 級數係數的一維陣列,從低到高排列。

步驟

首先,匯入所需庫 −

import numpy as np
from numpy.polynomial import hermite as H

建立 Hermit 級數係數的一維陣列 −

c1 = np.array([1,2,3])
c2 = np.array([3,2,1])

顯示係數陣列 −

print("Array1...\n",c1)
print("\nArray2...\n",c2)

顯示資料型別 −

print("\nArray1 datatype...\n",c1.dtype)
print("\nArray2 datatype...\n",c2.dtype)

檢查兩個陣列的維度 −

print("\nDimensions of Array1...\n",c1.ndim)
print("\nDimensions of Array2...\n",c2.ndim)

檢查兩個陣列的形狀 −

print("\nShape of Array1...\n",c1.shape)
print("\nShape of Array2...\n",c2.shape)

若要將一個 Hermit 級數加到另一個級數上,請在 Python Numpy 中使用 polynomial.hermite.hermadd() 方法 −

print("\nResult (sum)....\n",H.hermadd(c1, c2))

示例

import numpy as np
from numpy.polynomial import hermite as H

# Create 1-D arrays of Hermite series coefficients
c1 = np.array([1,2,3])
c2 = np.array([3,2,1])

# Display the arrays of coefficients
print("Array1...\n",c1)
print("\nArray2...\n",c2)

# Display the datatype
print("\nArray1 datatype...\n",c1.dtype)
print("\nArray2 datatype...\n",c2.dtype)

# Check the Dimensions of both the arrays
print("\nDimensions of Array1...\n",c1.ndim)
print("\nDimensions of Array2...\n",c2.ndim)

# Check the Shape of both the arrays
print("\nShape of Array1...\n",c1.shape)
print("\nShape of Array2...\n",c2.shape)

# To add one Hermite series to another, use the polynomial.hermite.hermadd() method in Python Numpy
# The method returns an array representing the Hermite series of their sum.
# Returns the sum of two Hermite series c1 + c2. The arguments are
print("\nResult (sum)....\n",H.hermadd(c1, c2))
