This isn't going to change. It would be inconsistent with the way we promote 1D arrays to higher dimensions when broadcasting (i.e. we always prepend 1s to the shape tuple so 1D arrays are treated like 2D row vectors). For the hstack() case, you might want to use column_stack() which explicitly treats 1D arrays like columns. Otherwise, just use column vectors explicitly. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
