## Issue

I want to create a vector in TensorFlow.js, which has the following structure:

where `a`

is a non-complex scalar, `n`

is the length of the vector, and `i`

is the `i`

-th entry of the vector, starting to count at zero.

Is there a fast way of doing this or do I need to loop?

## Solution

IIUC, you could try maybe something like this:

```
x = tf.tensor1d([1, 2, 3, 4, 5, 6, 7, 8]).toInt();
y = tf.range(0, x.shape[0], 1).toInt();
x.pow(y).print();
```

```
"Tensor
[1, 2, 9, 64, 625, 7776, 117649, 2097152]"
```
