Mike,

It is a good question.

Right now I am doing some of each.  If a function was defined in mlab.py 
and it has a replacement in numpy I am issuing a  deprecation warning 
and passing the arguments to the numpy function.  If a function was not 
defined in mlab but was imported from numerix, then, with a couple of 
exceptions, I am simply not leaving it in the mlab namespace.

This is in the present (old) mlab.py:

from numerix import array, asarray, arange, divide, exp, arctan2, \
      multiply, transpose, ravel, repeat, resize, reshape, floor, ceil,\
      absolute, matrixmultiply, power, take, where, Float, Int, asum,\
      dot, convolve, pi, Complex, ones, zeros, diagonal, Matrix, nonzero, \
      log, searchsorted, concatenate, sort, ArrayType, clip, size, indices,\
      conjugate, typecode, iscontiguous

For compatibility, access to some or all of these things may need to 
remain in the *pylab* namespace for a while, but I don't think it should 
stay in the *mlab* namespace as well.  I really don't want to add 
wrappers with warnings for all these functions.
