You don't need to use a recarray object to get "records". Any array can have "records". Therefore, you can have a masked array of "records" by creating an array with the appropriate data-type.
It may also be possible to use a recarray as the "array" for the masked array object becuase the recarray is a sub-class of the array. > I have tried with arrays of dtype=object, but I > have problem when I want to compute min, max, ... with an error like: > TypeError: function not supported for these types, and can't coerce safely to > supported types. > It looks like the max and min functions are not supported for Object arrays. import numpy as N N.maximum.types does not include Object arrays.
