Array processing function

I’d like to pass it an empty array and have the new array returned.

If you’re gonna return a new array, why would you need to pass an empty array?

You could simply return a new array regardless.

Besides, you’re actually passing an array w/ length 20 to your function coord():
float [] locArr = new float[20];
coord(locArr);

And inside coord() you fill up the array w/ a range value 0 to 1.
