Hello Everybody,
I need a function that returns non-NaN values from an array. Currently I am doing it this way:
>>> a = np.array([np.nan, 1, 2])
>>> a
array([ NaN, 1., 2.])
>>> np.invert(np.isnan(a))
array([False, True, True], dtype=bool)
>>> a[np.invert(np.isnan(a))]
array([ 1., 2.])
Python: 2.6.4 numpy: 1.3.0
Please share if you know a better way, Thank you
