subarray Function

Purpose:

Returns a new array that is a subset of the given array

Syntax:

newarray = subarray(input,position1,position2)

Comments: 

position 2 must be greater than position 1

Using this routine is much faster and easier to use than copying array items yourself in a loop

Example:

b2 = subarray(b1,aud.mark1,aud.mark2-aud.mark1)
