- ma.put(a, indices, values, mode='raise')[source]#
Set storage-indexed locations to corresponding values.
This function is equivalent to
MaskedArray.put
, see that method for details.See also
Examples
Putting values in a masked array:
>>> a = np.ma.array([1, 2, 3, 4], mask=[False, True, False, False]) >>> np.ma.put(a, [1, 3], [10, 30]) >>> a masked_array(data=[ 1, 10, 3, 30], mask=False, fill_value=999999)
Using put with a 2D array:
>>> b = np.ma.array([[1, 2], [3, 4]], mask=[[False, True], [False, False]]) >>> np.ma.put(b, [[0, 1], [1, 0]], [[10, 20], [30, 40]]) >>> b masked_array( data=[[40, 30], [ 3, 4]], mask=False, fill_value=999999)
