I have a dataset that contains a multidimensional array of shape (2400, 2).

I want to be able to take each of these 2400 rows, and modify them to be a range from the start and end points (the two elements in each of the 2400 rows). The range is always the same length (in my case, a length of 60).

For example, if I have something like this:

```
array([[  78,   82],
       [  90, 94],
       [  102, 106]])

```

My output should be something like this:

```
array([[  78, 79, 80, 81, 82],
       [  90, 91, 92, 93, 94],
       [  102, 103, 104, 105, 106]])

```

The only way I have been able to do this is with a for loop, but I am trying to avoid looping through each row as the dataset can get very large.

Thanks!
