support for copy.deepcopy()
  __nonzero__(self)
  __reduce__(self)
__reduce__ returns the pickling "reduction tuple" for an NDArray.
  astype(self, type)
  copy(self)
Return a new array with the same shape and type, but a copy of the data
  factory(self, *args, **keys)
factory(...) calls the array(...) factory function defined in the source module where the class of 'self' was defined.
  getflat(self)
  getrank(self)
  getshape(self)
  is_c_array(self)
is_c_array() returns 1 iff the array is aligned and contiguous, and returns 0 otherwise.

ravel(self) setshapes 'self' into an equivalent 1D array.
  repeat(self, repeats, axis)
repeat() returns a new array with each element 'a[i]' repeated 'r[i]' times.
  resize(self, shape, *args)
resize() shrinks/grows 'self' to new 'shape', possibly replacing the underlying buffer object.
  setflat(self, flat)
  setshape(self, shape, *args)
Change array shape in place.
  take(self, *indices, **keywords)
  tofile(self, file)
Write the array as a binary image to a file.
  tostring(self)
Return a string with a binary copy of the array
  transpose(self, axes)
transpose() re-shapes the array by permuting it's dimensions as specified by 'axes'.
  _arrayIndexing(self, key, value)
  _broadcast(self, arr)
Return broadcast view of arr, else return None.
  _clone(self, shape)
  _copyFrom(self, arr)
Copy elements from another array.
  _dualbroadcast(self, arr)
Return broadcast views both self and arr, else return (None,None).
  _fix_pt_indices(self, indices)
  _isSlice(self, key)
  _put(self, indices, values, **keywds)
  _stridesFromShape(self)
Compute the strides from shape for a contiguous array
  _take(self, indices, **keywds)
  _tofileByBlocks(self, file, dims, indexlevel, blockingparameters)
Write the array to a file repeatedly in blocks
