在Python中将一个Hermite级数乘以另一个

要将一个Hermite级数乘以另一个，请使用Python的polynomial.hermite.hermmul()方法Numpy。该方法返回一个表示其乘积的Hermite系列的数组。返回两个Hermite系列c1 * c2的乘积。参数是系数的序列，从最低阶“项”到最高阶，例如，[1,2,3]表示系列P_0 + 2 * P_1 + 3 * P_2的数组。这些参数是从低到高排序的Hermite系列系数的一维数组。

步骤

首先，导入所需的库−

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

创建Hermite级数系数的1-D数组 –

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

显示系数数组 −

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

显示数据类型 –

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

检查两个数组的尺寸−

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

检查两个数组的形状−

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

要将一个Hermite级数乘以另一个Hermite级数，可以在Python中使用polynomial.hermite.hermmul()方法 Numpy −

print("\nResult (multiply)....\n",H.hermmul(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 multiply one Hermite series to another, use the polynomial.hermite.hermmul() method in Python Numpy
# The method returns an array representing the Hermite series of their product.
print("\nResult (multiply)....\n",H.hermmul(c1, c2))
