Newbie Scala question about simple math array operations

Question

Newbie Scala Question:

Say I want to do this [Java code] in Scala:

public static double[] abs(double[] r, double[] im) {
  double t[] = new double[r.leng         


        

Answer 1

After Edit:

OK I have got running what I wanted to do. Will take two Lists of any type of number and return an Array of Doubles.

def abs[A](r:List[A], im:List[A])(implicit numeric: Numeric[A]):Array[Double] = {
  var t = new Array[Double](r.length)
  for( i <- r.indices) {          
    t(i) = math.sqrt(numeric.toDouble(r(i))*numeric.toDouble(r(i))+numeric.toDouble(im(i))*numeric.toDouble(im(i)))
  }
  t
}
