I am starting using scala
and I am interested in using the scalala
package for doing linear algebra computations. I successfully installed it through sbt
but I can't (or better don't know how) start the scalala console
. Can anyone point out the steps I have to take to make that possible?
Thanks a lot
P.S. I have read this quickstart guide but didn't help me.
[EDIT]
To be more clear I do not want to explicitly make includes with the standard scala
console in order scalala

UPDATE:
If you want start Scalala console without explicitly import those package, then maybe you need build a excutable jar directly from the GitHub repo.
The following steps should work:
git clone https://github.com/scalala/Scalala
cd Scalala
./sbt update compile proguard
java -jar target/scala_2.8.1/scalala_2.8.1-1.0.0.RC2-SNAPSHOT.min.jar
And now you should get an Scala console with Scalala package imported by default.
Since the document says the scalala console just a standard Scala console with default package imported.
You could just run sbt
under your project directory, and using console
command to enter Scala console mode.
Finally, type in the following code:
import scalala.scalar._;
import scalala.tensor.::;
import scalala.tensor.mutable._;
import scalala.tensor.dense._;
import scalala.tensor.sparse._;
import scalala.library.Library._;
import scalala.library.LinearAlgebra._;
import scalala.library.Statistics._;
import scalala.library.Plotting._;
import scalala.operators.Implicits._;
Now you should be able to use Scalala just like the document sayas.
run
java -jar target/scala_2.8.1/scalala*.min.jar
or the equivalent for your release of scalala. Optionally, you could run the standard scala console and type in the following includes
import scalala.scalar._;
import scalala.tensor._;
import scalala.tensor.mutable._;
import scalala.tensor.dense._;
import scalala.tensor.sparse._;
import scalala.library.Library._;
import scalala.library.LinearAlgebra._;
import scalala.library.Statistics._;
import scalala.library.Plotting._;
import scalala.operators.Implicits._;
Was there something beyond the instructions you were having an issue with? Citing specific errors or specific problems encountered is a great way to get a more specific answer.
