| #### 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 | ||||
| 
 | ||||
