Could numpy.matlib.nanmax return a matrix?

Is anybody interested in making x.max() and nanmax() behave the same
for matrices, except for the NaN part? That is, make
numpy.matlib.nanmax return a matrix instead of an array.


>> import numpy.matlib as M
>> x = M.rand(3,2)

>> x.max(0)
matrix([[ 0.91749823,  0.94942954]])

>> M.nanmax(x, 0)
array([ 0.91749823,  0.94942954])
