method
- ma.MaskedArray.compressed()[source]#
Return all the non-masked data as a 1-D array.
- Returns:
- datandarray
A new
ndarray
holding the non-masked data is returned.
Notes
The result is not a MaskedArray!
Examples
>>> x = np.ma.array(np.arange(5), mask=[0]*2 + [1]*3) >>> x.compressed() array([0, 1]) >>> type(x.compressed()) <class 'numpy.ndarray'>
N-D arrays are compressed to 1-D.
>>> arr = [[1, 2], [3, 4]] >>> mask = [[1, 0], [0, 1]] >>> x = np.ma.array(arr, mask=mask) >>> x.compressed() array([2, 3])
