# MXNet - Scala API

See the [MXNet Scala API Documentation](http://mxnet.io/api/scala/docs/index.html).

MXNet supports the Scala programming language. The MXNet Scala package brings flexible and efficient GPU
computing and state-of-art deep learning to Scala. It enables you to write seamless tensor/matrix computation with multiple GPUs in Scala. It also lets you construct and customize the state-of-art deep learning models in Scala,
  and apply them to tasks, such as image classification and data science challenges.

You can perform tensor or matrix computation in pure Scala:

```scala
   scala> import ml.dmlc.mxnet._
   import ml.dmlc.mxnet._

   scala> val arr = NDArray.ones(2, 3)
   arr: ml.dmlc.mxnet.NDArray = ml.dmlc.mxnet.NDArray@f5e74790

   scala> arr.shape
   res0: ml.dmlc.mxnet.Shape = (2,3)

   scala> (arr * 2).toArray
   res2: Array[Float] = Array(2.0, 2.0, 2.0, 2.0, 2.0, 2.0)

   scala> (arr * 2).shape
   res3: ml.dmlc.mxnet.Shape = (2,3)
```
