Unintended variable reference?

I think I spotted a small inconsistency here:
https://github.com/wendykierp/JTransforms/blob/master/src/main/java/org/jtransforms/dht/DoubleDHT_3D.java#L1254

It looks like this method intended to use columns instead of columnsl since there are separate variables dealing with the large arrays. Feel free to close this if I'm incorrect.

Same possible issue on this line of Float version also:
