[Numpy-discussion] arange and linspace could take an output array

Hi all, I have a few cases where an output array with samples for a linear envelope should be composed by several linear segments, each one the output of arange o linspace. It would be preferable in terms of performance to write this segments directly to subviews of the output array instead of generating temporary arrays and then copying them to the final one. So why don't provide output arguments for arange and linspace? Thank you in advance. Cheers, Carlos
