## NumPy: Array Object Exercise-131 with Solution

Write a NumPy program to split a given array into multiple sub-arrays vertically (row-wise).

Sample Solution:

Python Code:

``````import numpy as np
print("\nOriginal arrays:")
x = np.arange(16.0).reshape(4, 4)
print(x)
new_array1 =  np.vsplit(x, 2)
print("\nSplit an array into multiple sub-arrays vertically:")
print(new_array1)
```
```

Sample Output:

```Original arrays:
[[ 0.  1.  2.  3.]
[ 4.  5.  6.  7.]
[ 8.  9. 10. 11.]
[12. 13. 14. 15.]]

Split an array into multiple sub-arrays vertically:
[array([[0., 1., 2., 3.],
[4., 5., 6., 7.]]), array([[ 8.,  9., 10., 11.],
[12., 13., 14., 15.]])]
```
