# 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.]]
