This recipe helps you rank items in a multidimensional array using numpy

0

## Recipe Objective

How to rank items in a multidimensional array using numpy? This is also done in case of multidimensional array by using "matrix_rank". Lets understand this with practical implementation.

## Step 1 - Import library

``` import numpy as np ```

## Step 2 - Take a Sample array

``` Sample_array = np.array([[22,33,4],[55,66,77],[88,99,11],[98,76,54]]) print("This is a Sample array:","\n",Sample_array) ```
```This is a Sample array:
[[22 33  4]
[55 66 77]
[88 99 11]
[98 76 54]]```

## Step 3 - Get the rank

``` np.linalg.matrix_rank(Sample_array) ```
`3`
