Examples
>>> importnumpyasnp>>> importnumpy.maasma>>> a=ma.masked_equal([[1,2],[3,4]],2)>>> amasked_array( data=[[1, --], [3, 4]], mask=[[False, True], [False, False]], fill_value=2)>>> ma.getmaskarray(a)array([[False, True], [False, False]])Result when mask == nomask
>>> b=ma.masked_array([[1,2],[3,4]])>>> bmasked_array( data=[[1, 2], [3, 4]], mask=False, fill_value=999999)>>> ma.getmaskarray(b)array([[False, False], [False, False]])
