method
ma.MaskedArray.compressed()
Return all the non-masked data as a 1-D array.
Returns:datandarrayA new
holding the non-masked data is returned.
Notes
The result is not a MaskedArray!
Examples
>>> importnumpyasnp>>> 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])
