#### Tensor Operations with Propel ML
[Propel ML](http://propelml.org/) `tensor` objects can be transposed:
```js
var tensor = pr.tensor(aoa).transpose();
var col1 = tensor.slice(0, 1);
var col2 = tensor.slice(1, 1);
```
To export to a worksheet, `dataSync` generates a `Float32Array` that can be
re-shaped in JS:
```js
/* extract shape and float array */
var tensor = pr.concat([col1, col2]).transpose();
var shape = tensor.shape;
var farray = tensor.dataSync();
var ws = array_to_sheet(farray, shape, ["header1", "header2"]);
```
The demo generates a sample dataset and uses Propel to calculate the OLS linear
regression coefficients. Afterwards, the tensors are exported to a new file.
#### TensorFlow
[TensorFlow](https://js.tensorflow.org/) `tensor` objects can be created from
