[Numpy-discussion] Efficient scaling of array

Hello list,

is there a possibility to scale an array by interpolation,
automatically? For illustration a 1D-example would be an array of size
5, which is scaled to size 3:

before: [ 1,   2,   3,   4,   5 ]
          1/1  2/3
               1/3  1   1/3
                        2/3   1
after : [ 2.33, 5, 7.66 ]


The same thing should be possible in nD, with the obvious analogy. Is
there such a function in numpy?

Kind regards,
Johannes
