Since this post is to PyNGL talk, I am assuming that you are
concerned with PyNGL and not NCL.

get_MDfloat_array is in the PyNGL Ngl module. See:

http://www.pyngl.ucar.edu/Functions/Ngl.get_MDfloat_array.shtml

The color2 example shows a usage.

If you did an:

import Ngl

and not:

from Ngl import *

to use get_MDfloat_array you will have to qualify it like:

Ngl.get_MDfloat_array
