dask.array.ma.masked_equal

dask.array.ma.masked_equal(a, value)[source]

Mask an array where equal to a given value.

This docstring was copied from numpy.ma.masked_equal.

Some inconsistencies with the Dask version may exist.

This function is a shortcut to masked_where, with condition = (x == value). For floating point arrays, consider using masked_values(x, value).

See also

masked_where

Mask where a condition is met.

masked_values

Mask using floating point equality.

Examples

>>> import numpy.ma as ma  
>>> a = np.arange(4)  
>>> a  
array([0, 1, 2, 3])
>>> ma.masked_equal(a, 2)  
masked_array(data=[0, 1, --, 3],
             mask=[False, False,  True, False],
       fill_value=2)
