I have made changes in matplotlib svn to facilitate experimentation with the maskedarray module; I hope this will speed up the process of testing it and incorporating it into numpy as a replacement for numpy.core.ma.
mpl scripts now accept the switches --maskedarray and --ma to force the use of the corresponding modules when loaded via matplotlib.numerix.ma or matplotlib.numerix.npyma. The latter is a new module intended for internal use in matplotlib as we switch to exclusive use of numpy. It is needed so that people using numerix in their own code can still get whatever numeric package and associated masked array package they want, while internally we can use numpy and either numpy.ma or maskedarray. There is also a new rcParams['maskedarray'] boolean entry (default is False) for selection of the masked array module. It is commented out of matplotlibrc by default, and most mpl users can ignore it. For switching to numpy inside of mpl, the ma import statement is: import matplotlib.numerix.npyma as ma I have not yet actually made this change anywhere; it needs to be made module-by-module as part of the switch to importing numpy directly instead of via numerix. The npyma module and/or the import statement will need to change as maskedarray is moved from being a standalone package to a part of numpy, but this change should be quite easy and painless.
