Return : Return new matrix

Example #1 :
In this example we can see that we are able to put the value from in given matrix with the help of method `matrix.put()`.

 `# import the important module in python``import` `numpy as np``         ` `# make matrix with numpy``gfg ``=` `np.matrix(``'[64, 1; 12, 3]'``)``         ` `# applying matrix.put() method``gfg.put((``0``, ``1``), ``45``)``   ` `print``(gfg)`
Output:
```[[45 45]
[12  3]]
```

Example #2 :

 `# import the important module in python``import` `numpy as np``         ` `# make a matrix with numpy``gfg ``=` `np.matrix(``'[1, 2, 3; 4, 5, 6; 7, 8, -9]'``)``         ` `# applying matrix.put() method``gfg.put(``2``, ``43``)``   ` `print``(gfg)`
Output:
```[[ 1  2 43]
[ 4  5  6]
[ 7  8 -9]]
```
