[Numpy-discussion] 3D interpolation of large array
Sun Sep 13 19:51:03 CDT 2009
I have a large dataset (e.g., 70 x 500 x 500) and want to interpolate points
(for example to double the size). What it seems I want is:
: coords = array([newz, newy, newx])
: dout = np.map_coordinates(d, coords)
The problem is that mgrid can't do such a large set of values (at least on
my setup! MacBook Pro with 4Gig RAM). The error from the mgrid command is
"ValueError: dimensions too large."
My version of Numpy is numpy-1.3.0n1-py2.5-macosx-10.3 (from the Enthought
Is there any other way that I could do this?
