Ah sorry, I hadn't read carefully enough what you were trying to achieve. I think the double repeat solution looks like your best option then.
Considering that it is a lot shorter than fixing the tile() result, you are probably right (I've only now looked closer at the repeat() solution ;-). I'd still be interested in the performance - since I think none of the reshape or rollaxis operations actually move any data in memory (for numpy > 1.6), it might still be faster. Cheers, Derek
