You can try also scipy.interpolate.griddata (not the pylab's griddata!)

I tried this function and it works very similar to the interp2 function of matlab. The only problem is that my data are very peaky and the cubic version of griddata gives me big over/under-shoots. The matlab function does not gives me such behavior. Is there another high 2D order interpolator that could be used in this case ? Octave has a nice "pchip" option for interp2 that use piecewise cubic Hermite interpolating polynomial, but unfortunatly griddata does not have such option. Thanks Christine
