2011-10-18 Thread Chao YUE 
Thanks Olivier. but I don't know how can I check it in the code (not in an
interactive mode)?
I would like:

if ndarray a is a mased array:
  code 1
else
 code 2

thanks again,

Chao

You could simply check if it has a 'mask' attribute. You can also check if
it is an instance of numpy.ma.core.MaskedArray.
