A Sunday 20 January 2008, Nicholas escrigué:
I am trying to package a set of vector arrays into a single rec array with column titles. c = numpy.rec.fromarrays([a,b],names='a,b') the problem is there is no 'copy' argument in .fromarrays which I can set to False. i.e. is there a way to do this without the overhead of copying?
You can't because of implementation issues: a recarray is implemented as a row-wise object, so the copy is absolutely needed. BTW, perhaps column-wise recarray would be a great addition to NumPy, although I'm not sure whether this object would be much better than a dictionary of homogeneous arrays. Cheers, --
