Convert Array[Array[Double]] to Array[Double]

Question

How can I convert an array of arrays of doubles to just an array of doubles using Scala 2.10.4?

Convert: Array[Array[Double]] => Array[Double]

@monkjack It is not really the same. In OP's case, flatten is what he is looking for. — Jean Logeart

You can write something like this:

val src = Array(Array(1.2,3.4), Array(5.6, 7.8))

val result = for {
a <- src
b <- a
} yield b
