Consider a 2D Laguerre collection at factors (x,y) with 1D array of coefficient utilizing NumPy in Python

[ad_1]

On this article, we are going to Consider a 2D Laguerre collection at factors (x,y) with a 1D array of coefficient 

Laguerre.lagval2d technique

In Python, laguerre.lagval2d() is used to judge a 2D Laguerre collection at factors (x,y). the place coefficient_array is the enter NumPy 1D array with coefficients and factors known as x and y. The primary parameter generally is a listing of pointsSo now we have to offer two listing such that every listing has an x-point and y-point.The second parameter is an numpy array of coefficients ordered such that it’s of three Dimensions.

Syntax: laguerre.lagval2d(x,y,c)

Parameters:

  • x,y: array_like, appropriate objects
  • c: Array of coefficients.

Return: The values of the 2 dimensional polynomial at factors

Instance 1:

On this instance, we’re making a NumPy array with 5 coefficients to judge Laguerre Collection at factors [3,4],[1,2].

Python3

import numpy

  

from numpy.polynomial import laguerre

  

coefficient_array = numpy.array([45, 67, 54, 53, 15])

  

print(coefficient_array)

  

print(coefficient_array.ndim)

  

print(coefficient_array.form)

  

print(laguerre.lagval2d([3, 4], [1, 2], coefficient_array))

Output:

[45 67 54 53 15]
1
(5,)
[-42.375      -79.04166667]

Instance 2:

On this instance, we’re making a NumPy array with 6 coefficients and evaluating Laguerre Collection at factors [1,4],[1,2].

Python3

import numpy 

  

from numpy.polynomial import laguerre

  

coefficient_array = numpy.array([45,67,54,53,67, 15])

  

print(coefficient_array)

  

print(coefficient_array.ndim)

  

print(coefficient_array.form)

  

print(laguerre.lagval2d([1,4],[1,2],coefficient_array))

Output:

[45 67 54 53 67 15]
1
(6,)
[ -66.20833333 -141.875]
