numpy.ma.left_shift#
- ma.left_shift(a, n)[source]#
Shift the bits of an integer to the left.
This is the masked array version of
numpy.left_shift
, for details see that function.See also
Examples
Shift with a masked array:
>>> arr = np.ma.array([10, 20, 30], mask=[False, True, False]) >>> np.ma.left_shift(arr, 1) masked_array(data=[20, --, 60], mask=[False, True, False], fill_value=999999)
Large shift:
>>> np.ma.left_shift(10, 10) masked_array(data=10240, mask=False, fill_value=999999)
Shift with a scalar and an array:
>>> scalar = 10 >>> arr = np.ma.array([1, 2, 3], mask=[False, True, False]) >>> np.ma.left_shift(scalar, arr) masked_array(data=[20, --, 80], mask=[False, True, False], fill_value=999999)
