Hi,
I just noticed the following and I was kind of surprised:
>>>a = ma.MaskedArray([1,2,3,4,5], mask=[False,True,True,False,False])
>>>b = a*5
>>>b
masked_array(data = [5 -- -- 20 25],
mask = [False True True False False],
fill_value=999999)
>>>b.data
array([ 5, 10, 15, 20, 25])
I was expecting that the underlying data wouldn't get modified while masked. Is
this actual behavior expected?
