Given 2 arrays create a Cauchy matrix from it

So this recipe is a short example on how to create a Cauchy matrix from two arrays. Let's get started.

```
import numpy as np
```

Let's pause and look at these imports. Numpy is generally helpful in data manipulation while working with arrays. It also helps in performing mathematical operation.

```
x = np.array([1,2,3,4])
y = np.array([5,6,7])
```

Here, we have created two simple arrays.

```
c= 1.0 / (x.reshape((-1,1)) - y)
```

Now, using the formula, we have created a simple cauchy matrix.

```
print(c)
```

Now, simply using print function, we have print our matrix.

Once we run the above code snippet, we will see:
