OptiML with Scalala?

[Khobatha Setetemela]

Hi

I have across a Scala numerical library called Scalala[] with plotting capabilities.

I plan to experiment using this along with OptiML to make some simple data plots. So far, I have managed to compile Scalala and modified OptiML build settings to take Scalala as a library dependency.Running sbt update on OptiML after this works without errors.

Now, I am attempting to test this setup with a simple plotting code-snippet from Scalala, now wrapped inside an OptiML application.

// OptiML includes

import optiml.library._

import optiml.shared._

import optiml.compiler._

// Scalala 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._;

object MyScalalaInterpreter extends OptiMLApplicationInterpreter with MyScalala 

object MyScalalaCompiler extends OptiMLApplicationCompiler with MyScalala

trait MyScalala extends OptiMLApplication

{

  def main =

  {

    print("Hello! This is my first OptiML Application :)\n")

    

    val x = DenseVector.range(0,100) / 100.0;

    plot.hold = true

    plot(x, x :^ 2)

    plot(x, x :^ 3, '.')

    xlabel("x axis")

    ylabel("y axis")

    saveas("lines.png") // save current figure as a .png

  }

}

I cannot successfully compile this code.

In principle, before dealing with the error messages I am getting, should this OptiML-Scalala arrangement work?

Please advise.
