ma.compress_rows(a)
Suppress whole rows of a 2-D array that contain masked values.
This is equivalent to np.ma.compress_rowcols(a,0), see
for details.
Parameters:xarray_like, MaskedArrayThe array to operate on. If not a MaskedArray instance (or if no array elements are masked), x is interpreted as a MaskedArray with mask set to
. Must be a 2D array.
Returns:compressed_arrayndarrayThe compressed array.
Examples
>>> importnumpyasnp>>> a=np.ma.array(np.arange(9).reshape(3,3),mask=[[1,0,0],... [1,0,0],... [0,0,0]])>>> np.ma.compress_rows(a)array([[6, 7, 8]])
