  # Python | Numpy matrix.argmax ()

NumPy | Python Methods and Functions

Using the ` Numpy matrix.argmax () ` method, we can find the index value of the maximum element in a given matrix that has one or more dimensions.

Syntax: `matrix.argmax()`

Return: Return index number of maximum element in matrix

Example # 1:
In this example, we can see that using the ` matrix.argmax () ` we can find the index of the maximum element in the given matrix.

 ` # import important module into python ` ` import ` ` numpy as np `   ` # make a matrix with NumPy ` ` gfg ` ` = ` np.matrix ( ` `[1, 2, 3, 4]` ` `) `   ` # using the matrix.argmax () method ` ` geeks ` ` = ` ` gfg.argmax () `   ` print ` ` (geeks) `

Exit :

` 3 `

Example # 2:

 ` # import an important module into python ` ` import ` ` numpy as np `   ` # make a matrix with NumPy ` ` gfg ` ` = ` ` np.matrix (` ` `[1, 2, 3; 4, 5, 6; 7, 8, 9] `` `) ` ` `  ` # using the matrix.argmax () method ` ` geeks ` ` = gfg.argmax () ``   print (geeks) `

Exit :

` 8 `
