>>> import numpy.ma as ma >>> x = [11.2, -3.973, 0.801, -1.41] >>> mask = [0, 0, 0, 1] >>> masked_x = ma.masked_array(x, mask) >>> masked_x masked_array(data=[11.2, -3.973, 0.801, --], mask=[False, False, False, True], fill_value=1e+20) >>> ma.power(masked_x, 2) masked_array(data=[125.43999999999998, 15.784728999999999, 0.6416010000000001, --], mask=[False, False, False, True], fill_value=1e+20) >>> y = [-0.5, 2, 0, 17] >>> masked_y = ma.masked_array(y, mask) >>> masked_y masked_array(data=[-0.5, 2.0, 0.0, --], mask=[False, False, False, True], fill_value=1e+20) >>> ma.power(masked_x, masked_y) masked_array(data=[0.2988071523335984, 15.784728999999999, 1.0, --], mask=[False, False, False, True], fill_value=1e+20)
