Python | Numpy np.lagval2d() method
With the help of np.lagval2d() method, we can get the 2-D laguerre series at point x by using np.lagval2d() method.
Syntax :
np.lagval2d(x, y, c)
Return : Return the 2-D laguerre series at point x and y.
Example #1 :
In this example we can see that by using np.lagval2d() method, we are able to get the 2-D laguerre series at point x and y by using this method.
# import numpy and lagval2d import numpy as np from numpy.polynomial.laguerre import lagval2d x = np.array([[1, 2], [3, 4]]) y = np.array([[5, 10], [15, 20]]) c = np.array([1, 2]) # import np.lagval2d() method gfg = lagval2d(x, y, c) print(gfg) |
Output :
[[13. 44.] [43. 94.]]
Example #2 :
# import numpy and lagval2d import numpy as np from numpy.polynomial.laguerre import lagval2d x = np.array([[1, 2], [3, 4]]) y = np.array([[-1, -2], [-3, -4]]) c = np.array([1, -2]) # import np.lagval2d() method gfg = lagval2d(x, y, c) print(gfg) |
Output :
[[11. 24.] [21. 38.]]
