fixed wiki typo

MaskedArray is a numpy ndarray look-alike that allows one to keep track of missing values.

MaskedArray is implemented in numpy.core.ma module. The numpy ma module is originally written for Numeric by Paul Dubois and adapted for numpy by Travis Oliphant and (mainly) Paul Dubois.


Remaining Issues

Some of the same issues that were resolved in numpy need to be revisited for ma. (See Numeric3.0 Design Document)

  • What does single element indexing return? Scalars or rank-0 arrays?
  • Can arrays be used as truth values directly?
