What are the other options for such a repeat ? No, I don't think there are any other options. stride tricks are a bit hidden, since in many cases it is more dangerous than helping. Though with some care you can easily implement such functions using stride_tricks. Thanks ! Since it's in a buried helper function, I could use stride tricks. But for now I'll stick with broadcast_arrays because I have it working.
Maybe the np.repeat function could be changed to avoid copying (when possible) ?
I doubt it fits repeat well, since repeat also allows for repetition of single elements. The repeats that could be done like this are a few of the many ways repeat can be used. What may make sense is to add one or two thought out functions for common `as_strided` use cases, which always return valid arrays... - Sebastian
