## How to find maximum value in whole 2D array with indices?

**How to find maximum value in whole 2D array with indices?**Here, You can test the max value using the index returned, indices returned should look like

`(array([0], dtype=int64), array([2], dtype=int64))`

when you print the indices.**find maximum value in whole 2D array with indices**Here, You can test the max value using the index returned, indices returned should look like

`(array([0], dtype=int64), array([2], dtype=int64))`

when you print the indices.

## Method 1

which also elaborates how to find the max value and its (1D) index, you can use `argmax()`

>>> a = array([[10,50,30],[60,20,40]]) >>> maxindex = a.argmax() >>> maxindex 3

You can then use `unravel_index(a.argmax(), a.shape)`

to get the indices as a tuple:

>>> from numpy import unravel_index >>> unravel_index(a.argmax(), a.shape) (1, 0)

## Method 2

Here, You can test the max value using the index returned, indices returned should look like `(array([0], dtype=int64), array([2], dtype=int64))`

when you print the indices.

import numpy as np a = np.array([[200,300,400],[100,50,300]]) indices = np.where(a == a.max()) print(a[indices]) # prints [400] # Index for max value found two times (two locations) a = np.array([[200,400,400],[100,50,300]]) indices = np.where(a == a.max()) print(a[indices]) # prints [400 400] because two indices for max #Now lets print the location (Index) for index in indices: print(index)
