NaN in Numerical

[Huaiyu Zhu]

How to save and load a matrix containing NaN in the Numeric module?
Matlab/Octave treat these the same way as numbers.
In Python I use eval to load, which treats NaN as unknown variable name.

BTW, is there a searchable form of NumPy documentation?
It's not so easy to find info in the pdf format.

Thanks for any pointer.
