## NumPy: Array Object Exercise-187 with Solution

Write a NumPy program to convert a given vector of integers to a matrix of binary representation.

Pictorial Presentation: Sample Solution:

Python Code:

``````import numpy as np
nums = np.array([0, 1, 3, 5, 7, 9, 11, 13, 15])
print("Original vector:")
print(nums)
bin_nums = ((nums.reshape(-1,1) & (2**np.arange(8))) != 0).astype(int)
print("\nBinary representation of the said vector:")
print(bin_nums[:,::-1])
```
```

Sample Output:

```Original vector:
[ 0  1  3  5  7  9 11 13 15]

Binary representation of the said vector:
[[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 1]
[0 0 0 0 0 0 1 1]
[0 0 0 0 0 1 0 1]
[0 0 0 0 0 1 1 1]
[0 0 0 0 1 0 0 1]
[0 0 0 0 1 0 1 1]
[0 0 0 0 1 1 0 1]
[0 0 0 0 1 1 1 1]]
```
