gkthiruvathukal / arrays.scala
Created February 24, 2016 05:04
Trying to figure out the best way to create homogenous, n-dimensional arrays in Scala. Array.ofDim() not proving to be ideal.
/ This takes forever and seems to use a lot more memory than expected
Array.ofDim[Double](2048, 2048, 2048)
// This seems to work faster and uses less memory.
def get1d(d1 : Int, init : Double) = Stream.continually(init) take d1 toArray
def get2d(d1 : Int, d2 : Int, init : Double) = Stream.continually( get1d(d2, init) ) take d1 toArray
def get3d(d1 : Int, d2 : Int, d3 : Int, init : Double) = Stream.continually( get2d(d2, d3, init) ) take d1 toArray
// More testing is needed.
