Hello,

Could you please give me some hints about how to mask an array using another
arrays like in the following example.

In [14]: a = arange(5)

In [15]: a
Out[15]: array([0, 1, 2, 3, 4])

and my secondary array is "b"

In [16]: b = array([2,3])

What I want to do is to mask a with b values and get an array of:

array([False, False, True, True,  False], dtype=bool)

That is just an manually created array. I still don't know how to do this
programmatically in Pythonic fashion or numpy's masked array functions.

Thank you.
